I disagree with this. This creates a situation of; throw a punch, does he give up yet, throw another, ok, surely he wants to stop now. That's how you really get hurts. You've hit the other person so the fight so it's on, and now you're stopping.

Personally I would advice that you do whatever you can to avoid a fight, but if you must fight you go until the other person is incapacitated or you get separated (in school this happens really quick anyway). Once you start a fight all further reluctance has to go out the window or you're going to get hurt.
