🎯 What is Controller Drift?

Analog stick drift happens when potentiometers wear out or dust interferes, causing movement even when untouched. Our analog stick tester measures resting values — anything above |0.15| indicates drift.

Drift severity scale 0.00 = perfect
Healthy (0-0.15) Moderate (0.15-0.3) Severe (0.3+)

⚪ Dead Zones Explained

The dead zone is the area near center where movement is ignored. Our visualiser draws a faint 15% circle — if your stick rests inside, it's healthy.

Ideal resting position

Inside dashed line = no drift
