GR is well established to high accuracy.
This includes time dilation due to the earth's rotation
(reflected in the altitude of the geoid), and gravitational
redshift due to height above the geoid.

Tom, I understand that you believe there are other factors
involved in time dilation such as the geoid.
That is not a "belief", that is an experimentally observed _fact_.
$$ Yes. But it WAS NOT a FACT in ANY THEORETiCAL aspect, of GR.
Does the geoid or some other fudge apply in the twin paradox ?
The geoid is not a "fudge". And whether or not it applies to the
twin paradox depends on the physical situation being discussed
and the accuracy of measurement.
H&K compared their flying clocks with a stationary one in Denver.

Your number is wrong. But yes, one must take into account both
motion and gravitation when comparing clocks accurately. <shrug>
$$ NO. You *NEED* take into account ..*ONLY* the clock's ALTiTUDE.
There are many atomic clocks located in many countries.
Have they ever reported time dilation differences
Yes. You are supposed to read what I wrote (to which you are
responding). They must correct for altitude relative to the geoid, and
they do so all the time. <shrug>
$$ Yes. But there is NO "POiNT-mass TEST-geoid" ..in GR Tivity.
or does it only apply to theoreticals like the twin paradox?
See above. You must specify more precisely what you are thinking of.
The twin paradox is not merely "theoretical" -- it has been
experimentally observed (see the FAQ: Bailley et al, Haefle and
Keating, and also C.Alley).
