a common misconception in this game is that you should put players at 7 minutes when they max out. players have an improvement curve, and along that curve, rate of improvement and decrease are related. when rate of improvement is roughly 0, so is rate of decrease. so, if a guy has room for improvement in any meaningful category, put all capped categories at 0 minutes of practice. more than 90% of the time, you won't see a decrease, and when you do, its probably only because the category was on a border line (like it was 68.52 and dropped to 68.45).
