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

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