That'll teach me to read (more accurately "peruse") only a few posts on a
thread then post a follow-up...

Still, I'd have thought that doing this measurement in the "digital" domain
with a timer resolution of 500nS or better would produce better results than
in the audio domain with the associated noise and distortion etc.

After looking at the web page though I see the results look pretty good
though so things can't be that bad in audio-land. Neat.
