First of all, I'm sorry if this topic has already been discussed.
I know for a fact that FT, GS and Stamina training efficiency doesn't depend on the trainer level. But I think I've also read that it doesn't depend on the weekly minutes played as well, so that, for example, a player who's played 48 minutes will receive as much training as a player who didn't even see the court in a given week.
Is that correct?
