So looks like I'm a on average 200ms eye to finger mouse button clicker on a 60Hz display with 6ms click latency mouse. Strange thing is I can sometimes feel the slowness of my finger to respond, or maybe I'm just imagining it

Also tried some computer aided results by screenshots and color recognition. The results seemed oddly inconsistent and fastest I've seen is 2ms when taking into account the 6ms latency of the mouse button.

Averages improved with higher display refresh rate.
