I agree 100 %. The rationale is that the Internet is extremely variable.
If you get 0.1 s four times and a routing accident gives you 2.0 s one
time, the average will be 0.5 s (just one spike and you destroy the whole
sequence) and the mean 0.1 s, which gives a better idea of typical
response times.

Ad: echoping <> displays mean
and average. I use it to monitor Web and Squid response times. (For
instance <>.)
