How is the score calculated?

The 9c test measures four independent strength qualities. Each exercise scores 1–10 points (max 40 total), which maps to a climbing grade from 6a to 9c.

Exercise 1 — Finger strength (20mm edge, 5 sec)

Hang from a 20mm edge for 5 seconds. Score based on total weight as % of bodyweight:

7160%

Exercise 2 — Max pull-up (1 rep)

Same scoring as exercise 1. Add weight until you can only do 1 rep.
