I parsed this for something like 300 swings with and without, it sounds like it'd take a long time, but that's what Merc. Swords are for. Anyway, my average crit went from 108.6 to 111.3, which is +2.5% on the button. It's no where near a +10% increase, and I have no idea how someone could come to that conclusion. "Eyebaling it" is not a legit way of parsing things. Take note, PS2 players.
