Basicly Ahhnold needs to work out more and focus less on those unimportant things :p
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 :p
