The reason that he can get to the point of diminishing returns quickly
is that they nature of the platform means that point has a relatively
low time quality.
It's also a matter of what you consider sufficiently accurate - 1 second,
1 millisecond, 1 microsecond or whatever. Not everyone needs or wants
microsecond level accuracy.
Having said that, I don't recall my FreeBSD 8.0 system taking anything
like 10 hours to get to a few microseconds reported offset (this with a
GPS/PPS reference). Switching on the heating in the morning causes a ~10
microsecond jump, which (together with the room temperature) has settled
within the hour. See yesterday's graph around 0600 UTC:
