Pointer cancel, lost capture and a missing primary-button state are recorded separately. An early voluntary release is incomplete, not automatically a mouse fault.

This measures human reaction plus display, mouse, operating-system and browser event delay. It is useful for same-user comparisons, not device-only latency certification.

INFO

Complete the guided eight-second movement capture

No complete browser-delivered event distribution is available.

LIKELY CAUSES

The fixed capture window has not completed.

ACTIONS

Move in steady circles for the full guided capture.

RETEST CONDITION

Keep the pointer inside the surface until progress reaches 100%.

Actions are generated from visible Evidence fields and versioned product rules. They do not identify a physical root cause with laboratory certainty.

No raw axes, key logs, audio, video, images, full user agent or device ID is stored. Clearing browser site data also removes this history.

OPTIONAL TIPSImprove repeat checks0/3 checked

Optional. The test works without this; these tips only reduce comparison noise.

MEASUREMENT BOUNDARY

Useful evidence, without pretending to be a laboratory.

Event rate is browser-delivered, not direct USB polling.

OS acceleration can change movement deltas.

Some browsers reserve Back and Forward buttons.
