Then ntpd starts to correct the initial offset properly in less than 300

unfortunately at a 10 ms offset the filter algorithm seems to switch and
the following correction is still very poor compared to the initial
correction.

Martin, the 10 ms behavior is pretty much a given, since the OS clock works at the same 10 ms resolution!

The realtime thread hack to interpolate between OS ticks does help, but NTPD still needs a lot of statistical data to be able to settle down at offset values well below the OS tick!
