Touchscreens and mouse buttons use different sensors, event models and ergonomics, so scores are not directly interchangeable.
Touch input
A tap includes contact start, movement thresholds and release. Browsers may also suppress gestures or synthesize clicks.
Mouse input
A button produces discrete down and up events with switch debounce and USB reporting.
Best practice
Use device labels in rankings and compare within the same input type.
