Nice plots Brooke,
you can see the immediate loop compensation for the g-sensitivity. These EFC
steps are similar to what crystal jumps would look like.
The question is: does the probability of seeing jumps on an OCXO change with
the rotation/orientation of the OCXO. I suspect it does have some effect.

All kinds of things effect the crystal including gravity. Some time ago I
wrote a Labview program to look at the control voltage then rotated the

resting it on each of four faces, see:

So, just as gravity effects pendulum clocks, it's also effecting crystal
oscillators, just on a smaller scale.
