bb/100

Big blinds won or lost per 100 hands: a cash player's win rate.

What it means
bb/100 divides your result in big blinds by the hands you played and multiplies by 100, so sessions of any length and any stakes compare on one scale.
How it is calculated
bb/100 = result in bb ÷ hands × 100. The app shows it only once a session or a level has enough hands behind it, because a few dozen hands say almost nothing.
Worked example
Up 18bb over 120 hands is 18 ÷ 120 × 100 = 15 bb/100. Down 35bb over 70 hands is −50 bb/100.
Why it matters
Winning players at real 6-max tables sit somewhere around +2 to +10 bb/100 over tens of thousands of hands. Short-run numbers swing far more than that, so read them alongside your graded decisions.
