I see that after 10 years of training you are still excited about hitting somebody. It means you still don't understand that this aspect is completely useless as an indicator of "martial effectiveness" in cooperative environment.
Szczepan, do you mean that it isn't important if people are leaving openings where they can be hit? I understand why hitting people wouldn't be an indicator of martial effectiveness, and also that people sometimes use hitting to cover up errors, but I would have thought that if you and your partner are in a position where they can hit you, that's basically bad? Shouldn't you be trying to get behind them, and to get them off balance, etc?
