What this metric measures

Beat fit compares selected jump events with the nearest detected music beat within a configured tolerance. It is separate from general rhythm stability.

How Trampoline Lab calculates it

The system detects or imports a beat timeline, matches eligible jump events and reports matched rate plus timing error. Team mode can calculate each athlete before aggregation.

How to interpret it

A higher score means closer timing under the current tolerance. It does not mean the jump technique, height or landing was better.

Limits and responsible use

Audio quality, beat detection, chosen event type, tolerance and too few jumps can materially change the score.
