a human trying to double clic as fast as possible :
201 samples, with an interval from 100 to 130 ms

a double clic macro :
373 samples , all grouped in a close interval

we need more cases to have a clear idea, but the concept is the human is slow and not reliable whatever he tries
of course you can try to combine both macro and human actions
