Method
Counters describe browser events. Wheel deltas vary by browser and device, so this tool reports direction and event count rather than physical notch count.
Limitations
This does not measure clicks per second, DPI, hardware polling rate, sensor accuracy, calibration, or device identity. Touch and limited-pointer environments may expose fewer events.
Privacy
No account, server calculation, fetch, XHR, beacon, cookie, local storage, session storage, IndexedDB, device identifier, or user-value telemetry is used.
