Method: standard bb/100 win-rate formula · deterministic arithmetic — no AI
| Constant | Value | Source |
|---|---|---|
| netBb | sum of session results, in big blinds | your logged entries |
| handsPlayed | sum of hands played across entries | your logged entries |
bb100 = (netBb / handsPlayed) × 100// the standard cross-stake win-rate unit — normalizes for volumebb/100 only becomes a meaningful signal after enough volume — a few thousand hands still carries wide variance. All entries stay local to this device.
