For ovenized crystals, any oven temperature change will cause aging to temporarily increase (and may change the direction as well). Restabilization may take an hour to a day, depending on how much the temperature was changed. We haven't noticed that powering up the oscillator or not makes a big difference. (This refers to leaving the oven on, and turning off the oscillator circuitry. This experiment is easy to do on a 10811 since the supplies are separate.) Does that answer your question?
