It's the same thing as kicking someone in the head with your ankle in aikido and your foot snaps and the opponent ends up with the most points from that kick...

So yes, there are some obvious glitches every here and there, and with a second-check on the damage most of it could HOPEFULLY be fixed; is it plausible that kicking someones head would deal you more damage than the opponent, if the answer is no, redo the calcs...

But that's another problem in itself that needs to be treated accordingly.
