Okay, just checking.
I should have qualified that and said "vs. another force user" (otherwise we'd have to count the battles against stormtroopers, Jabba's guards, etc).
Yoda did grimace a few times, and he looked pissed when he threw that lightning, but nobody has ever tried to claim he was "dabbling in the Dark Side" which is surprising, but a fair point!
Btw, love your avatar. I've still got that box somewhere!
