My first "A" in pokergrader

[MaxPowerPoker]

I scored my first "A" in PokerGrader. Surprise, it was a losing session. Drat!

Pokergrader on several occasions has kept me from giving up poker for good. I will usually submit hands for a losing session just to see if I'm still "good". It convinces me that I am and I keep at it. My results over the last several weeks should have me looking for another hobby, but good ole PokerGrader says my potential profit is a bazillion BB/100. Gotta stick it out until the green line and the red line converge.

Do any of you guys use PokerGrader this way - basically to check to make sure you don't all of a sudden suck at poker?
