Alright, I can't let this thread die.
I *think* I found out how to determine stealing winrate in terms of BB/100.
From the general tab in "stats" I go to filter. There's a filter you can check that says "chance to steal blinds." I select "chance to steal & raised" and as I understand it, that changes your stats to situations where you had the chance to steal and actually made a raise to do that.
Then, back on the main page you can see your winrate in those unique situations.
Anyway, my suspicion that blind steal were a big part of my success is true. I'm actuallly winning more in steal situations. Remember, I said I was attempting steals at a rate of 35% and was winning 65% of those hands.
My winrate in terms of bb/100 when making steals is 2.21 / 100 hands. That is just slightly more than my overall winrate.
TP, please use this filter and compare your bb/100 in the blinds to your overall.
