Field notes
The homepage groups 6 keyboard tools and 6 mouse tools, with separate categories for gamepad and performance tests. Its examples include chatter timing, ghosting/NKRO, spacebar speed over 5–30 seconds, and comparing a gamepad result after changing only the connection; the page says repeat checks are limited to suspicious results.
