I'm sorry for posting nonsense like this. People who remember how a
typical ADEV plot looks like (with the -1 and +1/2 slopes) probably
knew this was wrong. It should be only 100x shorter polling interval
for 1000x smaller jitter (a slope of 2/3).

I think PTP using 128 sync messages per second is more about filtering
measurements (effectively decreasing the jitter), rather than
the instability of the clock.
