Warm-up: (at -20=C2=B0C) (at 25=C2=B0C)
Time to Lock: < 8.7 min < 5.4 min
Time to <1E-9: <10.2 min <7.3 min
Time to <4E-10: <12.7 min <10.6 min

Frequency Retrace: <=C2=B12.5E-11
(after 24 hrs power on @ 25=C2=B0C & up to 48 hrs power off)

I guess my readings are all within the above specs. The retrace value is
probably the limiting factor. 2.5E-11 translates in my setup to 90ns/hour.
Which looks being reached already in about 2 hours after power-on. So if
the Efratom is essentially the same as the Datum, then all looks fine.
