Each time I have a bad session (more than 2k hands) I go to the games notes in PT and try to figure if I am running bad or if I'm on tilt/FPS. I simply replay all the hands with a pot > 20bb won or lost. Most of the time it's variance and sometimes I can see how bad I can play when I'm on tilt. When I have an hesitation about the way I played a hand I ask to friends or I post the hand on the forum.

When the downswing last for more than 10k I try to check deeper :
_ I look at all my pp and see how many times I hit a set on the flop while holding a pp. This should be roughly 12%. I have been as low as 8% over 10k hands.
_ I look at the frequency of the big winning hand : QQ+/AK. _ I look at all the classical setup loose/win a stack and see if i'm even. I'm thinking about set over set, KK vs AA, flush over flush (with two cards of course), str8 over str8 and things like that.
_ I look at my AI with drawing hands and AI against drawing hand.

These kinds of checking can help you to:
_ Stay confident in your game which is really important when you are running bad.
_ Find out when you are on tilt much quicker.

Last but not least : I use the grindhouse thread to whime.
