Ratings and Attributes
Attributes are those quantities we can give +5 to in a skill camp and are not visible to GMs. Ratings are visible to GMs as letter grades and are composed of attributes as follows:
Inside Scoring = 50% Inside Scoring + 20% Strength + 30% Jumping
Outside Scoring = 50% Jump Shot + 50% Three Point Shot
Handling = (67% Passing + 15% Quickness) * (1 + 0.5% * Handling)
Rebounding = 45% Defensive Rebounding + 35% Offensive Rebounding + 15% Strength + 5% Quickness
Defense is roster position dependent as follows:
Any attribute exceeding the roster position's cap will not factor into the player's defensive grade, but will have an impact on the court. When a player changes roster position and gets + or -, this is why. Handling attribute has a notch that treats 61 Handling as 51 Handling for grade calculation purposes, as well as diminishing returns above 61. Again, this does not mean the player has gotten worse, just that grades can be deceiving. Finally, attributes are hard capped for roster positions as follows:
C_: 75 handling, 75 passing, 75 perimeter defense
PF: 80 handling, 80 passing, 75 perimeter defense
SF: none
SG: 60 offensive rebounding, 60 defensive rebounding
PG: 50 offensive rebounding, 50 defensive rebounding, 75 post defense
An attribute cannot exceed a roster position's hard cap either through training camp growth or skill camp / reward camp. However, under certain circumstances a player can be at a different depth chart position than roster position. Only the player's roster position caps apply.
Minimum Rating Needed for Each Grade
The software enforces a minimum rating of 1 and maximum rating of 100, as well as a minimum attribute of 5 and maximum attribute of 100.
Attribute Change over Time
Every player has a hidden and visible potential. Visible potential is calculated after each training camp as hidden potential / 2 + 25 ± 15, with the last term a random range from +15 to -15: 32.5% from +2 to -2, 65% from +14 to +3 and -3 to -14, and 2.5% for +15 and -15. The only value that matters for attribute growth is the hidden potential after training camp. Ending hidden potential from 0 to 20 is tier one, 21 to 40 tier two, and so on to tier five. Here are the maximums for per position at the time of training camp per tier:
The minimum values are -5 for these attributes for all tiers. All distributions are symmetrical except for Inside Scoring, which is skewed down.
Quickness, Strength, and Jumping have different ranges depending on the attribute entering TC: -5 at 100, +4/-4 at 90, +3/-3 at 70, +2/-2 at 50, +1/-1 at 20. This is where the attributes were tested, not necessarily where the breakpoints are. They are unaffected by position or tier of growth. They are affected by age: a -1 is applied at age 30+ and an additional -1 is applied at age 36+.
Jump Shot depends on the attribute entering TC and position and tier:
Hidden potential itself for veterans in their twenties changes from -7 to -10 for hidden potentials from 71 to 100, -4 to -7 from 51 to 70, and +5 to -5 from 1 to 50. For those in their thirties, a -3 is applied. For those in their teens, only the 71 to 100 range is different with four evenly weighted possibilities:
-decrease of potential / 5
-decrease of between -2 and -6
-stay the same
-increase of between +1 and +20
Current Rating
The software combines all of a player's characteristics into one single number called Current Rating, which is hidden from GMs. It does not do so in a way that accurately reflects a player's contributions on the floor. Current Rating determines roster order within a position, so the highest C will have the highest Current Rating.
.
Testing
I check each position from two perspectives.
BAD
-Create a player with fifty less than his position's maximum in every attribute and record eighty seasons.
-Increase one attribute to the maximum and record eighty seasons.
-Return that attribute to fifty less than max, increase the next attribute to the maximum and record eighty seasons.
-Repeat for every attribute.
GOOD
-Create a player with the maximum in every attribute and record eighty seasons.
-Reduce one attribute by fifty and record eighty seasons.
-Return that attribute to the max, reduce the next attribute by fifty and record eighty seasons.
-Repeat for every attribute.
I specifically recorded player [games, minutes, field goals, field goal attempts, free throws, free throw attempts, three pointers, three point attempts, rebounds, assists, steals, blocks, turnovers, fouls, points] and team [wins, points allowed, turnovers allowed, field goals allowed, field goal attempts allowed, free throw attempts allowed, points, turnovers, field goals, field goal attempts, free throw attempts]. This allows me to calculate usage by team and player as well as Pythagorean wins in addition to actual wins.
.
Results
Usage
Usage is functionally capped: the GOOD regime only shows usage changes when Inside Scoring or Strength are reduced. Attributes increase usage mostly in the area suggested by their rating, but Inside Scoring for example will also increase jump shots and passes to a lesser degree. This table is given in [tenths of a use per 36 minutes to the nearest half-use] from [fifty points of an attribute].
Minutes Played
Minutes played are based on two fundamental principles. First, a coach will give more playing time to a player he thinks deserves it, and it turns out that he makes this judgment on a very strict attribute by attribute basis for each position. These numbers are given below in terms of multiplicative increase in MP per fifty points of attribute. Second, a referee will send off a player that accumulates six personal fouls, and so attributes that decrease fouling will increase playing time. In both cases, minutes are functionally capped at about 38 minutes per game for bigs and 40 minutes per game for perimeter players.
Most attributes are irrelevant to fouling. There are no offensive fouls in the software.
Shot Blocking decreases for everyone.
Perimeter Defense slightly increases for everyone.
Quickness, Post Defense, and Strength increase for perimeter players and decrease for bigs.
Injuries
No attribute helps avoid injury. The more a player plays, the more likely they are to be injured.
Wins
Tested for players who are BAD. This table is given in [tenths of a Pythagorean win] from [fifty points of attribute] in one year.
Tested for players who are GOOD.
Granular Results per Attribute
This is going to get pretty intense. The way I recommend reading this chart is to go column by column, and those columns are [rebounds, assists, steals, blocks, turnovers, personal fouls, points] per 36 minutes, usage%, points per true shot attempt, assists per turnover, defenses per personal foul, % of uses that ended in [field goal attempt, turnover, free throw attempts, three point attempt], free throw %, three point %. It's a lot of information, but I'll give some examples below.
So let's look at "ast" first. It turns out that a player can only generate so many assists, so a bad player can increase their ast/36 with eight different attributes, but a good player can only increase assists with Passing. We also see evidence of non-linear effects: a 50 Inside Scoring 50 Passing player will see more assists from an increase in Inside Scoring, but a 100/100 player will see more from a decrease in the same attribute. A similar story occurs in usage %.
Two interesting wrinkles that are not obvious from the attribute descriptions. Quickness affects every grade except Scoring, but it turns out to increase 3P% and not increase rebounds. I guess it's possible Quickness' impact on rebounding refers to boxing out and so it might help team rebounding or something, but I doubt it. The second interesting one is that Defensive Rebounding increases free throw rate, which one would normally associate with Offensive Rebounding. Because the software doesn't split out rebounds into offensive and defensive there's no way to know for sure, but my guess is that each Rebounding helps on each side of the ball, it's just slanted one way or the other. Thus Offensive Rebounding helps free throw rate more, but Defensive Rebounding still helps it.
.
Overall Recommendations
The following tables are ultimately subjective. I have listed what I feel are the relevant result of increasing attribute relative to others available to the position:
gain is the expected team wins generated
growth is how quickly the attribute can be expected to grow naturally
mp is whether the attribute will be rewarded by the coach with more playing time
usage is how much the attribute can be expected to increase the player's usage
point guard
shooting guard
small forward
power forward
center
Keep in mind that Shot Blocking and Three Shot are nonlinear - a player who doesn't do them at all will see little impact from a small increase.
.
Measureables
An average center was tested at 140, 240, and 340 pounds. One thing changed: FG%, and at about the rate of 0.1% (.001) per 5 pounds, so each 100 pounds of weight was worth 2%. Literally every other stat was identical.
An average center was tested at 5'11", 6'11", and 7'11". One foot of height makes for about 0.3 more rebounds per 36 minutes, 0.2 less blocks per 36 minutes, and 1.5 more team wins per season, most of which come on the offensive end, but height does help team defense. In terms of overall contribution a foot of height is very roughly worth about 500 Strength.
An average point guard showed similar results.
.
Depth Chart
Pace:
Faster: More possessions, higher scoring, higher FG%, more free throws drawn, more shots taken from three
Slower: Less possessions, more assists, slightly less turnovers per possession
If team A scores more points per possession on average than team B, a faster pace further favors team A because a larger sample size will push the actual values closer to the expected values: it's plausible for a 50% FT shooter to go 2 of 2 and an 80% shooter to go 1 of 2, it's prohibitively unlikely for them to go 200 of 200 and 100 of 200 respectively.
Scoring Focus:
23% C_ / 23% PF / 18% SF / 18% SG / 18% PG - inside
18% C_ / 18% PF / 21% SF / 20% SG / 23% PG - balanced
15% C_ / 15% PF / 19% SF / 24% SG / 27% PG - outside
These values are a baseline. Specific players will shoot more or less than the average depending on their attributes. Overall, a team will have more threes, less free throws, and less turnovers the further outside your focus is. In a very fast paced outside focus:
Press: Pressing doesn't work. Opponents get more assists and more points per true shot attempt, a pressing team gets less blocks, more fouls, and no additional turnovers forced.
Trapping: Trapping works. Opponents don't shoot worse, but will turn the ball over more and assist less without drawing more fouls. A trapping team will focus more on steals than blocks and so the rate of shots blocked will go down slightly, but the tradeoff is worth it. The whole team will trap, not just bigs, and perimeter players will see more defensive improvement overall, but trapping is good for every good defender.
Minutes
Better players and especially players who score a lot of points will play more minutes than worse players. The software only really cares about the first two healthy players listed at a given position. If we test three DC types over a three season simulation...
A: starter / backup / backup
B: starter / backup / starter
C: starter / backup / utility
...the starters and backups played 99.7%, 99.7%, and 99.6% of the available minutes, and the starters played 77%, 77%, and 77%. A team can squeeze out about 15 seconds per game by putting a given starter at other position's third strings, but at the cost of 4 minutes per game being played by players the software coach selects even if everyone stays healthy. This can be a very significant cost because the software coaches make truly inexplicable decisions: for example playing a C Handling PF at PG when a B+ Handling PG was available on the bench but not on the DC. The third string will come into play even more when injuries occur, especially for mid-sim and short term injuries where DC adjustment isn't possible.
Scoring Option
A better description would be Playmaking Option, because making a player a scoring option will increase both their shot attempts and pass attempts. Players who already have high usage will not see as big a bump by being a given Scoring Option, and the first Scoring Option provides the biggest bump. Gain in usage from being a scoring option also depends on position and focus.
Gain refers to being a #1 option. #2 options get about 75% and #3 options get about 40% of the effect. Loss refers to another player being a #1 option, and the same ratios apply to them being #2 and #3 options. The max for a starter is thus being a #1 option when the other options are third stringers, and the min is three other starters being scoring options.
There is no usage/efficiency trade off in the software, and a player will not change shot selection based on being an option. A player will be as efficient as a 1st option as a non option.
Depth Chart Position
Two otherwise identical players listed at PF and C on the roster will have identical production if each are listed at PF on the depth chart, or each listed at C, or each listed at PG (this is illegal, don't do this).
An identical player listed at different depth chart positions will see production change in the following ratios regardless of offensive focus.
Rebounds: bigs 520, wings 420, point 390
Blocks: bigs 60, wings 30, point 25
Fouls: bigs 210, wings 110, point 90
Steals: shooting guards 90(!), centers 60, everyone else 70
Three Point %: bigs 30%, small forwards 27%, guards 25%
The player will also see production change depending on inside, balanced, and outside focus.
FTA/use: bigs, wings, point. In order of offense the splits were 10/7/6, 8.5/6.5/5, 8/6/5.
TOV/use: bigs, wings, point. 14/16/23, 14/16/19, 15/15/16
3PA/use: small forward, shooting guard, point, bigs. 14/12/11/7, 16/15/13/10, 19/17/15/13
.
Players and Contracts
An age 34 or lower player under contract will never retire in the following offseason. An age 35+ player has between a 25% and 50% chance to retire, regardless of Current Rating. Age 35-37 are verified 25% and age 43 is verified 50%. Players not under contract can retire younger.
When a league starts, every team has a 50 Win Rating.
After the playoffs are completed in every season, a team's Win Rating is (wins + 10 * playoff rounds won + 5 * championship won).
At some point in the offseason, a team's Win Rating is the average of the past year's starting and finishing values rounded to the nearest even number.
Players are marked in the software as resigning after day 120 and before the playoffs, which is before the team's new Win Rating is calculated.
Offering to resign is based only on Current Rating:
89.5% for 01-10 CRtg
85% for 41-50
75% for 51-60
60% for 61-70
50% for 71+
There is no correlation from loyalty, play for winner, or win rating to anything to do with resigning. There is significant correlation between greed and contract length and size, but not offering to resign at all.
Free Agency
Contract raises are generated by multiplying the previous year's value by the percent, but they are capped at the sum of the first year's value multiplied by the percent. For example, a contract of 6 years, $12.5m, 9% is
$12,500,000
$13,625,000 (1.09 * the previous value)
$14,851,250 (1.09 *)
$16,187,862 (1.09 *)
$17,500,000 (only 1.081 * the previous value because 12.5m+4*1.25m < 16.1m*1.09)
$18,750,000 (only 1.071 * for the same reason)
First year dollar amount is the most important factor, with enough of a gap the higher amount will win exactly 100% of the time, and players with higher greed will have larger responses to a given gap. Total amount in and of itself does not matter, but later years do: 5yr $6m will never beat 1yr $10m, but a 2yr $9m will often (not always) beat 1yr $9m, and for 0 greed players a 6yr $8m 10% will tie a 6yr $10m 0%.
There are many arbitrary break points where a losing but otherwise competitive offer will instead win 0%. One is a piecewise and irregular function of player greed and salary cap / 381, and that's the simple one. Try not to think about it.
Loyalty refers to the player's last team, not hometown. A team with Bird rights trying to retain a player with 50 greed and 50 loyalty with a 7yr $12.5m bid against another team with a 6yr $12.5m 10% bid will win as a function of raises:
00% - 8%
03% - 38%
05% - 70%
07% - 91%
10% - 99%
MAX - 100%
The same scenario with 7yr $12.5m 5% raises for an array of greeds and loyalties results in the Bird team winning as:
It is not the case for this set of contracts that an equal amount of greed balances an equal amount of loyalty.
As more non Bird teams bid, the total non Bird chance of winning increases (so long as every non Bird bid has more than 0% chance of success) but each individual non Bird team's chance decreases.
.
Software Players
When there aren't enough manually created players for a draft, the software will fill in randomly generated prospects with certain constraints depending on position:
These are the maximum and minimum values. The distributions are not symmetric. Averages are usually slightly below the midpoints except for Inside Scoring, where the average is far below the midpoint.
Attributes are those quantities we can give +5 to in a skill camp and are not visible to GMs. Ratings are visible to GMs as letter grades and are composed of attributes as follows:
Inside Scoring = 50% Inside Scoring + 20% Strength + 30% Jumping
Outside Scoring = 50% Jump Shot + 50% Three Point Shot
Handling = (67% Passing + 15% Quickness) * (1 + 0.5% * Handling)
Rebounding = 45% Defensive Rebounding + 35% Offensive Rebounding + 15% Strength + 5% Quickness
Defense is roster position dependent as follows:
caps qui ste sho poD peD drD str
c 45 65 85 85 55 80 85
pf 50 60 85 80 55 80 75

sg 40 35 20 40 35 30 15 215
pg 40 35 20 35 45 30 15 220
Any attribute exceeding the roster position's cap will not factor into the player's defensive grade, but will have an impact on the court. When a player changes roster position and gets + or -, this is why. Handling attribute has a notch that treats 61 Handling as 51 Handling for grade calculation purposes, as well as diminishing returns above 61. Again, this does not mean the player has gotten worse, just that grades can be deceiving. Finally, attributes are hard capped for roster positions as follows:
C_: 75 handling, 75 passing, 75 perimeter defense
PF: 80 handling, 80 passing, 75 perimeter defense
SF: none
SG: 60 offensive rebounding, 60 defensive rebounding
PG: 50 offensive rebounding, 50 defensive rebounding, 75 post defense
An attribute cannot exceed a roster position's hard cap either through training camp growth or skill camp / reward camp. However, under certain circumstances a player can be at a different depth chart position than roster position. Only the player's roster position caps apply.

The software enforces a minimum rating of 1 and maximum rating of 100, as well as a minimum attribute of 5 and maximum attribute of 100.
Attribute Change over Time
Every player has a hidden and visible potential. Visible potential is calculated after each training camp as hidden potential / 2 + 25 ± 15, with the last term a random range from +15 to -15: 32.5% from +2 to -2, 65% from +14 to +3 and -3 to -14, and 2.5% for +15 and -15. The only value that matters for attribute growth is the hidden potential after training camp. Ending hidden potential from 0 to 20 is tier one, 21 to 40 tier two, and so on to tier five. Here are the maximums for per position at the time of training camp per tier:

Minutes played are based on two fundamental principles. First, a coach will give more playing time to a player he thinks deserves it, and it turns out that he makes this judgment on a very strict attribute by attribute basis for each position. These numbers are given below in terms of multiplicative increase in MP per fifty points of attribute. Second, a referee will send off a player that accumulates six personal fouls, and so attributes that decrease fouling will increase playing time. In both cases, minutes are functionally capped at about 38 minutes per game for bigs and 40 minutes per game for perimeter players.

No attribute helps avoid injury. The more a player plays, the more likely they are to be injured.

Granular Results per Attribute
This is going to get pretty intense. The way I recommend reading this chart is to go column by column, and those columns are [rebounds, assists, steals, blocks, turnovers, personal fouls, points] per 36 minutes, usage%, points per true shot attempt, assists per turnover, defenses per personal foul, % of uses that ended in [field goal attempt, turnover, free throw attempts, three point attempt], free throw %, three point %. It's a lot of information, but I'll give some examples below.
So let's look at "ast" first. It turns out that a player can only generate so many assists, so a bad player can increase their ast/36 with eight different attributes, but a good player can only increase assists with Passing. We also see evidence of non-linear effects: a 50 Inside Scoring 50 Passing player will see more assists from an increase in Inside Scoring, but a 100/100 player will see more from a decrease in the same attribute. A similar story occurs in usage %.
Two interesting wrinkles that are not obvious from the attribute descriptions. Quickness affects every grade except Scoring, but it turns out to increase 3P% and not increase rebounds. I guess it's possible Quickness' impact on rebounding refers to boxing out and so it might help team rebounding or something, but I doubt it. The second interesting one is that Defensive Rebounding increases free throw rate, which one would normally associate with Offensive Rebounding. Because the software doesn't split out rebounds into offensive and defensive there's no way to know for sure, but my guess is that each Rebounding helps on each side of the ball, it's just slanted one way or the other. Thus Offensive Rebounding helps free throw rate more, but Defensive Rebounding still helps it.

Overall Recommendations
The following tables are ultimately subjective. I have listed what I feel are the relevant result of increasing attribute relative to others available to the position:
gain is the expected team wins generated
growth is how quickly the attribute can be expected to grow naturally
mp is whether the attribute will be rewarded by the coach with more playing time
usage is how much the attribute can be expected to increase the player's usage

Keep in mind that Shot Blocking and Three Shot are nonlinear - a player who doesn't do them at all will see little impact from a small increase.

Measureables
An average center was tested at 140, 240, and 340 pounds. One thing changed: FG%, and at about the rate of 0.1% (.001) per 5 pounds, so each 100 pounds of weight was worth 2%. Literally every other stat was identical.
An average center was tested at 5'11", 6'11", and 7'11". One foot of height makes for about 0.3 more rebounds per 36 minutes, 0.2 less blocks per 36 minutes, and 1.5 more team wins per season, most of which come on the offensive end, but height does help team defense. In terms of overall contribution a foot of height is very roughly worth about 500 Strength.
An average point guard showed similar results.

Depth Chart
Pace:
Faster: More possessions, higher scoring, higher FG%, more free throws drawn, more shots taken from three
Slower: Less possessions, more assists, slightly less turnovers per possession
If team A scores more points per possession on average than team B, a faster pace further favors team A because a larger sample size will push the actual values closer to the expected values: it's plausible for a 50% FT shooter to go 2 of 2 and an 80% shooter to go 1 of 2, it's prohibitively unlikely for them to go 200 of 200 and 100 of 200 respectively.
Scoring Focus:
23% C_ / 23% PF / 18% SF / 18% SG / 18% PG - inside
18% C_ / 18% PF / 21% SF / 20% SG / 23% PG - balanced
15% C_ / 15% PF / 19% SF / 24% SG / 27% PG - outside
These values are a baseline. Specific players will shoot more or less than the average depending on their attributes. Overall, a team will have more threes, less free throws, and less turnovers the further outside your focus is. In a very fast paced outside focus:
pg sg sf pf c loc
.15 .21 .16 .26 .26 close
.67 .60 .61 .57 .57 midrange
.18 .19 .23 .17 .17 three
Press: Pressing doesn't work. Opponents get more assists and more points per true shot attempt, a pressing team gets less blocks, more fouls, and no additional turnovers forced.
Trapping: Trapping works. Opponents don't shoot worse, but will turn the ball over more and assist less without drawing more fouls. A trapping team will focus more on steals than blocks and so the rate of shots blocked will go down slightly, but the tradeoff is worth it. The whole team will trap, not just bigs, and perimeter players will see more defensive improvement overall, but trapping is good for every good defender.
Minutes
Better players and especially players who score a lot of points will play more minutes than worse players. The software only really cares about the first two healthy players listed at a given position. If we test three DC types over a three season simulation...
A: starter / backup / backup
B: starter / backup / starter
C: starter / backup / utility
...the starters and backups played 99.7%, 99.7%, and 99.6% of the available minutes, and the starters played 77%, 77%, and 77%. A team can squeeze out about 15 seconds per game by putting a given starter at other position's third strings, but at the cost of 4 minutes per game being played by players the software coach selects even if everyone stays healthy. This can be a very significant cost because the software coaches make truly inexplicable decisions: for example playing a C Handling PF at PG when a B+ Handling PG was available on the bench but not on the DC. The third string will come into play even more when injuries occur, especially for mid-sim and short term injuries where DC adjustment isn't possible.
Scoring Option
A better description would be Playmaking Option, because making a player a scoring option will increase both their shot attempts and pass attempts. Players who already have high usage will not see as big a bump by being a given Scoring Option, and the first Scoring Option provides the biggest bump. Gain in usage from being a scoring option also depends on position and focus.

PF/C 151 121 20 272 108
Gain refers to being a #1 option. #2 options get about 75% and #3 options get about 40% of the effect. Loss refers to another player being a #1 option, and the same ratios apply to them being #2 and #3 options. The max for a starter is thus being a #1 option when the other options are third stringers, and the min is three other starters being scoring options.
There is no usage/efficiency trade off in the software, and a player will not change shot selection based on being an option. A player will be as efficient as a 1st option as a non option.
Depth Chart Position
Two otherwise identical players listed at PF and C on the roster will have identical production if each are listed at PF on the depth chart, or each listed at C, or each listed at PG (this is illegal, don't do this).
An identical player listed at different depth chart positions will see production change in the following ratios regardless of offensive focus.
Rebounds: bigs 520, wings 420, point 390
Blocks: bigs 60, wings 30, point 25
Fouls: bigs 210, wings 110, point 90
Steals: shooting guards 90(!), centers 60, everyone else 70
Three Point %: bigs 30%, small forwards 27%, guards 25%
The player will also see production change depending on inside, balanced, and outside focus.
FTA/use: bigs, wings, point. In order of offense the splits were 10/7/6, 8.5/6.5/5, 8/6/5.
TOV/use: bigs, wings, point. 14/16/23, 14/16/19, 15/15/16
3PA/use: small forward, shooting guard, point, bigs. 14/12/11/7, 16/15/13/10, 19/17/15/13

Players and Contracts
An age 34 or lower player under contract will never retire in the following offseason. An age 35+ player has between a 25% and 50% chance to retire, regardless of Current Rating. Age 35-37 are verified 25% and age 43 is verified 50%. Players not under contract can retire younger.
When a league starts, every team has a 50 Win Rating.
After the playoffs are completed in every season, a team's Win Rating is (wins + 10 * playoff rounds won + 5 * championship won).
At some point in the offseason, a team's Win Rating is the average of the past year's starting and finishing values rounded to the nearest even number.
Players are marked in the software as resigning after day 120 and before the playoffs, which is before the team's new Win Rating is calculated.
Offering to resign is based only on Current Rating:
89.5% for 01-10 CRtg
85% for 41-50
75% for 51-60
60% for 61-70
50% for 71+
There is no correlation from loyalty, play for winner, or win rating to anything to do with resigning. There is significant correlation between greed and contract length and size, but not offering to resign at all.
Free Agency
Contract raises are generated by multiplying the previous year's value by the percent, but they are capped at the sum of the first year's value multiplied by the percent. For example, a contract of 6 years, $12.5m, 9% is
$12,500,000
$13,625,000 (1.09 * the previous value)
$14,851,250 (1.09 *)
$16,187,862 (1.09 *)
$17,500,000 (only 1.081 * the previous value because 12.5m+4*1.25m < 16.1m*1.09)
$18,750,000 (only 1.071 * for the same reason)
First year dollar amount is the most important factor, with enough of a gap the higher amount will win exactly 100% of the time, and players with higher greed will have larger responses to a given gap. Total amount in and of itself does not matter, but later years do: 5yr $6m will never beat 1yr $10m, but a 2yr $9m will often (not always) beat 1yr $9m, and for 0 greed players a 6yr $8m 10% will tie a 6yr $10m 0%.
There are many arbitrary break points where a losing but otherwise competitive offer will instead win 0%. One is a piecewise and irregular function of player greed and salary cap / 381, and that's the simple one. Try not to think about it.
Loyalty refers to the player's last team, not hometown. A team with Bird rights trying to retain a player with 50 greed and 50 loyalty with a 7yr $12.5m bid against another team with a 6yr $12.5m 10% bid will win as a function of raises:
00% - 8%
03% - 38%
05% - 70%
07% - 91%
10% - 99%
MAX - 100%
The same scenario with 7yr $12.5m 5% raises for an array of greeds and loyalties results in the Bird team winning as:
L / G 0 50 100
0 44 24 16
50 95 70 46
100 100 96 79
It is not the case for this set of contracts that an equal amount of greed balances an equal amount of loyalty.
As more non Bird teams bid, the total non Bird chance of winning increases (so long as every non Bird bid has more than 0% chance of success) but each individual non Bird team's chance decreases.

These are the maximum and minimum values. The distributions are not symmetric. Averages are usually slightly below the midpoints except for Inside Scoring, where the average is far below the midpoint.
