Fixing Contact-Time Threshold Misdetection in Reactive Jump Tests

A force or accel threshold set too high shortens ground contact time and inflates RSI; set too low, it does the opposite. Here's how to find the right value.

Dual Force Plates: When Crosstalk Fakes an Asymmetry

A 'weak' side on a dual force-plate CMJ can be crosstalk between plates, not real asymmetry. Here's the swap-side test that tells them apart.

Load Cell Hysteresis Is Making Your IMTP Scores Read Low: How to Diagnose and Re-Zero It

Repeated IMTP trials reading lower each time? Load cell hysteresis and zero creep between pulls could be why. Here's how to test for it and re-zero correctly.
