The frequency correction that ntpd reports is the difference between the
free running clock frequency and the disciplined frequency, so should have
the full variability of the undisciplined clock.  The figures he quotes
are unremarkable for an undisciplined PC crystal in a temperature buffered,
but not closely controlled, environment.

One would hope that two GPS disciplined oscillators would track each other's
frequencies much much better than this.
