Re: Olympic data

This is why, at least in major meets, there is a speaker behind each runner
that carries the sound of the starting 'gun'.

And then there is the issue of the time difference for the sound of
the report of the starting gun to arrive at each of the starting
locations of the ears of the various runners. When the runners are
initially spread out all over the track this could be a significant
difference when the speed of sound is only some 340 m/s (0.01 s for
every 11 ft of difference in distance in the runners' starting
positions to the starting gun).
