30%, but I think I'm getting better at recognizing when I'm off my game.

I've found when I'm on I'm saying things like "he didn't raise preflop, so I doubt he has the ace, so that means my pair of 10's is probably good", etc.

When I'm off I say things like "How could he play crap like that? God, what a suckout. Idiot freaking called down with a pair of twos, what was he thinking? I can't belive AK lost AGAIN!"

Not entirely in jest. When I'm off I find my brain isn't quick enough to understand what's going on and my play ends up too much like a maniac or a calling station.
