Hi Mark:

Reaction time for a one off event like a starting pistol is different than to a repetitive event.  For example when 
hearing the seconds ticks the 1 PPS edge can be set to within milliseconds on a clock that has that capability.

Have Fun,

> Last month there was a discussion here about using a GPS to drive a hyper-accurate nixie tube clock with a lot of the discussion revolving around the effects of human perception and reaction times.   Here is blog post that discusses some of the gotchas software and hardware can impose.  There are some links near the end to some papers covering reaction times.
