How to test
Measure a straight movement on your desk and enter that distance and unit. Hold the button in the test area, move that distance, then release. Escape exits pointer lock.
What the result means
The estimate divides browser-reported movement by the entered distance in inches. Pointer scaling, acceleration, zoom and browser units affect it; this is not a sensor CPI measurement.
What to do next
Repeat in the same direction with unchanged settings. Compare the manufacturer's setting separately. Do not treat disagreement as proof of sensor damage.
