01 · Measure
Signals, not browser double-clicks
The test records the time between raw pointer presses. It does not rely on the browser’s double-click event.
02 · Interpret
100 ms diagnostic boundary
A rapid signal is evidence worth retesting, not proof by itself. Intentional fast clicking can produce the same result.
03 · Protect
Filter only what is necessary
The suggested filter rounds above the fastest suspicious gap. Retest before replacing hardware.
