Starter get's 36 min, sub get's 10 min, reserve get's 2 min. I'm not going to get into how to fill the slots, but I will add that when assigning someone starter and sub he will get only 41 minutes (adding reserve to that you get 43).
If you are the winning team with correct spot assignement you get full minutes. If you are the one throwing the game you do not get any minutes.
He is misinformed?
