People being people, if you ask for a 85 pitch count for your kid and he stays under 95 you have done well. Run after the game to eliminate lactic acid to minimize soreness, take asprin the next day if needed.
Dick Mills pitch count guidelines are optomistic in my very humble opinion. Allowing a high school pitcher go 106 pitches a week in two games max is fine for me. He should know what the limits are. His kid has been cut on, more than once I think.
