Variance...

[ashmc2]

I use this excuse all the time. Especially when I really get my ass kicked for a few days. Then I remember that my ADD was kicked in and I was calling everything down because I wasn't watching the board attentively.

No really - variance can only be noted with your normal playing style over a large set of hands. Any nontypical plays shouldn't be added to the set win or lose. But shit plays is a whole new sub-set to calculate.
