So now basically once a player reaches towards the end of 9* there is no more need to push them hard in training because the game will not let them game any more skill progress, so now the optimum strategy for power training is to time it perfectly that the player reaches the end of 9* right at the very end of the season so we don't lose some skill progress because a player has reached it's quality limit for the current level, your best off training players to mid-tier 9* now.
