Calibrate
Choose which phase to calibrate for this athlete. You can do these on separate days — progress is saved after each phase.
Phase 1
Warm-up
Normal warm-up at moderate effort. Measures natural RMSSD jitter at rest-ish intensity. Recommended 1:30 — editable below.
Not done yet
Phase 2
High-Intensity Drill
Maximal-effort drilling. Measures jitter at match intensity — combines with Phase 1 for adaptive sensitivity. Recommended 1:15 — editable below.
Not done yet
Phase 1 of 2 — have this athlete do their normal warm-up (realistic match intensity, no rest, no pressure) for 2 minutes 30 seconds. This measures natural RMSSD jitter at moderate effort.

For sharper accuracy, add a high-intensity drill so sensitivity can adapt to effort level during play — or save now and do it later.
