Methodology

How we measure

Every AllMouseTester score is produced in your browser from standard web APIs. Here is what that means — and what it does not.

Pointer, CPS and buttons

Click counts use pointerdown/mousedown events. Double-click windows follow the browser’s timing unless a tool exposes a slider. Chatter detection looks at inter-click gaps; it cannot see firmware debounce inside the mouse.

Polling rate & latency

We timestamp coalesced and raw pointer events and derive Hz and movement latency estimates. Browsers, USB stacks and display VSync all clamp the ceiling. Treat in-page Hz as a comparative browser measurement, not a replacement for a hardware USB analyser.

dpi

DPI/CPI checks need a known physical travel (card or ruler). Sensor angle, surface and OS acceleration (if left on) skew results — we recommend turning enhancement off for the test.

Audio & camera

Mic and webcam tools use getUserMedia. Meters show what the OS delivers after its own AGC/echo pipeline. We do not upload buffers.

Tay cầm

The Gamepad API reports axes and buttons; drift tests sample stick rest positions. Circularity and calibration quality vary by browser permission and controller firmware.

Reproducibility

Record browser, OS and tool URL with any score you publish. Re-run three times and prefer the median. See also About và Liên hệ.
