Rhythm measures your average timing deviation when tapping along to a metronome. It's a direct benchmark of sensorimotor timing.

A metronome plays at 100 BPM. After a four-beat count-in, tap along with every beat as precisely as you can for 16 beats.

Your primary score is the average absolute deviation between your taps and the nearest beat in milliseconds (lower is better), estimated against population norms.

Audio latency and input device affect timing. This is a research-grounded benchmark (Evidence B).
