Formula
Cash: BB/100 = (net BB won / hands) × 100. Tournament: ROI = (profit / buy-ins) × 100.
Example
A player with a 5 BB/100 realized win rate over 100,000 hands has high confidence they are a winning player. The same realized number over 10,000 hands does not — variance dominates short samples.
