Anyway, it depends on the guy. This is a good time for me to say that I train people SLOWLY. Because I want them doing things correctly, not just doing them just to do them and then I try to correct it. I have a kid right now I've been working with for about a month and a half and I still won't let him throw his right hand, because there's things I need to correct about his posture and ability (or inability) to execute movements. So all he has are 3 punches, all with his left hand that he can throw well. If he sparred, any time he threw his right he'd be subject to getting beaten-up. So it's all about progress. If I see it enough that it satisfies me, then a guy can go fight. If I don't, or if I see ANY inconsistency, then they don't get the reward of a fight.
