Turn a climbing session into a repeatable performance score using route difficulty, completion style, attempts, and number of successful climbs. Select the scale you record, enter the hardest completed grade as a numeric index, and note whether it was an onsight, flash, or redpoint. The score is designed for your own session history; it does not claim equivalence between every grading system or climbing style.
Attempt factor = 0.7 + 0.3 ÷ attempts. Volume bonus = min(successful climbs, 20) × 2.
The score rewards harder climbing, more demanding completion styles, fewer attempts, and useful session volume. Its best use is comparing your own sessions recorded with the same conventions.
Climbing grades are subjective and vary by area, setter, style, and conditions. Do not treat the score as an official cross-discipline ranking.
A YDS grade index of 12, redpointed in 3 attempts with 6 successful climbs, scores 116.0 points: 13 × 10 × 0.8 + 12.
It is the numeric value you consistently assign to a grade so the calculator can perform arithmetic.
No. The scale label records context; you must use a consistent index within that scale.
An onsight requires completing the climb first try without prior route-specific information, so this model weights it more.
Direct comparison is not recommended because grades and performance demands differ.
The cap keeps many easy completions from overwhelming the hardest-send component.
