It depends...a significant portion of his awake time here, anyway. Even ten minutes is too much if he's truly not comprehending why he's there and why his actions aren't acceptable. He's here from 9:30 until about 4 and sleeps for 2 to 2.5 hours, and we're outside for at least one hour (where the problems are still present, just in smaller form because there are fewer projectiles available). So, if I have to put him in there just three times because of throwing or hitting, it's a pretty good chunk of time when he doesn't seem to understand.
