- The drift test samples resting stick values for three seconds; the circularity test asks users to trace the stick edge three times.
Field notes
The interface exposes individual checks for button inputs, stick drift, circularity, deadzone, vibration, calibration, and polling rate rather than only a single controller-health indicator. It says the drift check samples resting values for three seconds and the calibration sequence takes about 15 seconds. The site also says readings remain in the browser; the supplied page extract does not demonstrate a successful test with a connected controller.
