Basicly Ahhnold needs to work out more and focus less on those unimportant things
More to the point, the game is basicly based on rolls for just about everything from dealing damage to calculating the chance to get a serious injury trigger and actually making one. Big possibility Ahhnold got the short end of the stick and Flonne made a high roll, can't say for sure unless I bother reading all of my glads fights thoroughly again. Especially Ahhnold vs Flonne
