I doubt if the counter is off frequency, since I'm using the 1pps pulses
from my GPSDO as its timebase. So although there's a bit of short-term
jitter, the longer-term count should be very close.
I will try the experiment you suggest, though, and see what difference
inversion makes to the frequency swing before locking (or non-locking).

What was the timebase for your counter? I suspect that it is off freq and
the Rb is not actually making it above 10 MHz. Inverting the Rb is causing
a 2G shift in gravity to the Rb crystal probably shifting its freq enough to
