I generated the following table from testing 40 yard dash times with a stopwatch of the AI with 90 speed 90 acc HB vs 80 speed, 80 acc LB:
| Setting | Threshold | HB | LB | Diff |
| Varsity | 0 | 4.11 | 4.63 | 0.52 |
| 50 | 4.02 | 4.49 | 0.47 |
| 100 | 4.03 | 4.35 | 0.3 |
| Heisman | 0 | 4.31 | 4.8 | 0.48 |
| 50 | 4.3 | 4.62 | 0.325 |
| 100 | 4.16 | 4.35 | 0.19 |
This tells us several important facts:
1) Players are faster on varsity than heisman regar(AA is in between; not shown here). By adjusting the difficulty level the computer is just improving the attributs of the AI not actually increasing the difficulty of the game. Designers have previously stated that this is how the difficulty works but I wanted to actually show that. They have also previously stated that the exact way it works is to boost the AI and penalize the human on Heismann, no effect on AA, and boost the human and penalize the AI on Varsity:
--Varsity boost attributes of human controlled players
--Varsity likley penalizes AI attributes
--Heismann penalizes human players attributes
--Heismann likely boosts AI players attributes
2) The gap of combine players between HB and LB is about 0.16 seconds to 0.19 seconds. For players in pads and given poorer speed on Defense in college lets make a goal of 0.25. Even on default of Heismann gap is too large this is made much worse on varsity where the AI appears to be much faster at HB relative to LB (perhaps the attribute boost is a % and not an absolute).
--Default threshold is too big but not too bad at Heismann
--Default threshold is much too large on varsity
--Threshold slider appears ot have a similar impact on the % change of speeds around an unknown value at either varsity of heismann.
--Threshold of 0 negatively impacts the speed differential.
3) HB get faster as threshold increases. This is even more noticable with linebackers. This means that the threshold slider does NOT move players closer together around a median/mean value but rather pushes all players statistics towards 99 compressing speed values (i.e. it makes all players <99 faster), conversely a lower threshold makes all playres even those at 90 slower stretching teh difference.
--Threshold shortens the gap or increases the gap around a value of 99 not around a value of 90.
--WR at 99 are not getting slower, CB at 90 are getting faster as threshold approaches 100
--WR at 99 are not getting faster, CB at 90 are getting slower as threshold approaches 0
