I'd bet any musician could do better than 0.1 sec.  If you are playing
piano and the timing of a note is off by as much as .1 sec it sounds
like an error.    MIDI is used to record musical performances and it
uses a "tick" about every 10ms or 100 or 128 per second. That is about
the range of human hearing, if you are good, delays smaller seem to us
a simultaneous.   I'd say that people who pratice every day such as
pianists could get to the 0.01 second range
