Keep both sticks untouched during center calibration. A practical deadzone recommendation is center drift + a small safety margin.

Interpretation
~0–3% center drift is usually easy to mask with a small deadzone. Higher values can become visible in games with raw or low-deadzone input. This page does not diagnose electrical faults.
