you are assuming direct observation. Sure, a human (normally) doesnt
notice smaller than say 10-20 msec of lag. But, a human very much
notices indirect effects of latencies, such as the nasty 'click' a
soundcard produces if it overruns.

a couple of msecs easily even on fast boxes. Well over 10 msecs on
slower boxes.
