On my XK-3c the keys full range of motion at the front edge is 8/16". The notes when set at the shallow trigger point sound at 2/16" and when set at the deeper setting trigger at 5/16".

On my System lower manual the full range is a little more than 7/16", and the trigger points are 3/16" and 5/16".

On my SK-1 the full range of travel is 7/16" and the notes (organ and EV) trigger at 5/16"

I used a piece of 3/5 card and a pencil to mark the key positions so give me +/- 1/64" or so margin of error.
