That number is the frequency CORRECTION applied by ntpd.

The fact this this value is stable is much more important than the value
itsself.

That's simply not true. 

ntpd is able to apply a frequency correction of between -500 ppm and
+500 ppm.

As long as you are not operating at the margins (i.e. close to +/- 500)
ntpd will be able to discipline your clock.
