I still don't understand.
Do you mean that if I train something like Free Throws for instance I will see improvements in less days, or in other words, each week I will improve more than in other positions?
For example, playing a player the necessary minutes to reach the training level will net me 2 points in free throws and only 1 point in say jump range?
Can someone explain this more and if possible provide a link to a page showing the ideal training times/point improvements for each rating?
