Alright. I have a down and dirty formula for player improvement just using WE and Practice minutes. Feel free to add or subtract a point per rating if is high/high instead of black. This formula is assuming the player has 15 or more points left to grow at the start of the season.
WE=W
Practice Minutes=P
Improvement=Y
(W/7)*P=X
-.0000000215X^4+.0000131X^3+-.00256X^2+.23416X=Y
Some examples:
67 WE, 15 P= 10.5 points of improvement
99 WE, 20 P= 20.2 points of improvement
16 WE, 20 P= 6.5 points of improvement
70 WE, 12 P= 9.4 points of improvement
3 WE, 20 P= 1.8 points of improvement
