It's usually measured in Poker tracker BB per 100. A PTBB is twice the big blind. so if you're playing 1/2 and you are winning 5 PTBB/100 you will be winning $20 every 100 hands you play. 5 PTBB/100 is imo considered pretty good to flipping good depending on what stakes you play.
Well I just played a 2 hour session 4 tabling the 10 cent 25 cent tables
After a horrendous outdraw on THE FINAL HAND I was reduced to $24.05 profit over 560 hands
That means I was making about 4.20 per hundred hands. so is that 8 big blinds? Cant be that good surely?
BTW thanks for the information, much appreciated
