EV loss per 100
How many big blinds your mistakes cost, on average, for every 100 decisions graded by EV.

- What it means
- The headline number for how well you play. It adds up the EV you gave away and scales it to 100 decisions, like a win rate in reverse.
- How it is calculated
- EV loss per 100 = total EV loss ÷ EV-graded decisions × 100. Only decisions with EV data count, so frequency-graded chart spots cannot dilute it.
- Worked example
- Over 250 push/fold decisions you gave away 30bb in total. 30 ÷ 250 × 100 = 12bb per 100. Next week it is 6bb per 100: your mistakes cost half as much.
- Why it matters
- Accuracy treats folding aces and a close mistake as equally wrong. EV loss weighs each mistake by what it costs, so it is the number to drive down.
