Reflection from the ionosphere nakes unpredictable changes in
polarization. Nevertheless, the angle of arrival equals the angle of
reflection at the ionosphere. Experience shows best results on a
transmission path happen when the antennas at both ends of the path are
complimentary. See E.A. Laport, "Radio Antenna Engineering" page 215,
"High Frequency Antennas".

I have no problem with what you state when dealing with skip,
But not all antennas use the skip phenomina such as satellite
antennas,MRO antennas or those used for weather conditions
and wind shear nd ofcourse any helical design antenna
.. What I was pointing out that if one was
looking for maximum gain of a specific structure then the
tipping angle comes into play. If you are looking for "max gain"
without reference to what type of structure of polarization
then yes, go ahead and do the standard axis parallel to the
ground method if you wish. I believe that most radio hams recognise
that a vertical polarised antenna is not the best type to use
when commnicating over ground with horizontally polarised antennas
and I suspect that even CBers are aware of that to.
