I notice such things...even that net control of the Sunday 20 meter TT net
is always 20 Hz low in frequency on his Jupiter! And I hate it when I'm in
a round-table or a net and not everyone is on the same frequency...even 10
Hz is noticeable to me. The Orions drift about 20 Hz during a warm up
period that takes up to three hours (unless you do my fan mod) at 15 MHz
WWV, which equates to 40 Hz on 10 meters. If you're driving a transverter
for multi-mode on two meters, that results in 200 Hz drift, which is way
into 'Donald Duck' territory!

If we want real frequency stability, here is what is needed:

After fretting over a few Hz for a while, I'm beginning to wonder why it
matters so much, other than being able to measure it in so many parts ber
gezillion and be able to just dial in the result for an FMT entry?
How did ham radio ever survive having only 5 Khz dial markings on the
radios
(if you were lucky), and even if you could afford the really good stuff
might be within a Khz or so? :-)
