i assumed yesterday wen i hit 3116 and got 0xp from what i thought was a "perfect fight" that it was my max. I played again seeing the 3120 score and realized i could increase mine as well. I don't know about the 2 player scenario. Increasing the sensitivity, from what i heard, could make you put less effort into your swings, and still do crutial, hard hitting damage. Ill update my Wii tommaro and check.
