How accurate is the browser-based polling rate test?

Browser-based polling rate tests use high-resolution timestamps from the Pointer Events API. Up to 1000Hz, browser tests are extremely accurate (within 1–2%). Above 2000Hz, browser event loop timing becomes the limiting factor.

Why is my double click test registering false positives?

False positives happen if you click faster than ~50ms naturally or if Windows pointer precision or software macros are active. Try slow, firm, deliberate single clicks — if it still flags, your switch has genuine chatter.

Can I test a wireless mouse?

Yes! All tools work with wireless mice — 2.4GHz dongle, Bluetooth, and wired USB. Note: Bluetooth mice typically have 10–30ms higher click latency than 2.4GHz wireless.

What does "issue detected" mean?

The "issue detected" verdict triggers when the measured click interval or latency falls into a suspect hardware fault zone based on statistical thresholds validated against known-faulty hardware.

How accurate is the DPI checker without special hardware?

By moving your mouse a measured physical distance (1 inch) with OS pointer acceleration disabled, the calculated DPI will be within 95–98% of your actual sensor output.
