Field notes
The diagnostic samples browser WheelEvent data while the test area is focused, then separates event count, direction, timing, delta magnitude, and delta units in its dashboard. Users can choose 15-, 30-, 45-, 60-, 90-, or 120-second runs and compare saved observations after changing one variable. Its interpretation is deliberately bounded: the page measures what the browser delivered, not hardware polling, and warns that touchpad inertia can be normal.
