The specs that I found here:

say the electrical EFC range is > 0.1 PPM, but that's for the version
with the D/A converter. I can't find any hint about our version.
My unit is starting to settle down. Yesterday aging was in the e-8
range, today it's in the e-9 range. Spec is < 2e-10/day.
Earlier I babbled something about a 200 Hz tuning range. I don't know
what I was thinking. The tuning range is 5 MHz +3 Hz to -7 Hz. So far
the drift has been upwards so I have lots of room to slow it down.
