The maximum offset with the linear smear was almost three times larger

I fear that test has sufficient power to reveal the full picture.
The NTPD PLL is quite temperamental, and when combined with the
median filter and a poll rate of 2048 seconds, things can get quite
"interesting".
I'm pretty sure that the linear smear interacts better with the
median filter at high poll intervals.
I'm going to run a test with a linear approach, too.
Please run it with "minpoll N maxpoll N" for N in (4...11)
Will do. However, for a general picture we'll need results for different
smear intervals, linear or cosine smearing for each interval, as well as
several polling intervals on the clients for the combination of each of
the above.
This will take some time.
