What this test checks
How to use this test
Move quickly inside the box. Keep moving while collecting samples, then check the interval graph.
What the results mean
Average rate uses positive event intervals. Median and jitter describe consistency; peak is the fastest observed interval.
Troubleshooting
Try another surface, port, connection mode, browser, or operating-system pointer setting.
Browser limitation
This is browser-observed event rate, not actual USB polling rate. Coalescing, timestamp precision, display timing and background throttling affect results. Compare in a foreground tab.
