I took a little time to get some stats:
-- the double tap time can be very subjective (affected by age?), but mine kept lax varied from 100ms to 350ms, with an average and median of 250ms. I think that to keep the "timedelta" value at
800ms will be safe.
-- the tap displacement in pixels, I think I well guessed it with 50:
7% of the deltas were beyond 40px, which means a success rate in double-click action of 85%;
4% of the deltas were beyond 50px, which means a success rate in double-click action of 90%; a few were beyond 60px. I attach a chart.
EDIT: a bit more empirically:
30px → 80% ; 35px → 85% ; 40px → 89% ; 50px → 93% ; 60px → 95%
EDIT2: I removed the former image because it was shamefully wrong. The distribution revealed to be a logarithmic distribution (10000 cases will err within 20, 1000 within 40, 100 within 80, 10 within 100 ... ).
