Ya I think you are right. Def doesn't happen very often, and there is almost always a point deduction involved. Are maybe there has to be ina three rounder...never though about that.
Well if there is a 10/8 round because one fighter coompletely dominates, then the other two rounds are 10/9 in favor of the other fighter, you get a draw. But I don't think mma judges give out 10/8 rounds all that much.
