First, I think that if you modeled a ground mounted vertical and the same

(take off angle) would not be the same for the two installations (just my
guess).
This makes sense to me. Can the NEC-based modeling
programs do that ? They seem to consider different
ground conditions... but what if ground is 350 feet away ?
Good question.
Second, so far no one has said anything about grayline DX (or about that
time) when some claim that a dipole works better than their vertical. This
is on the low bands, dont know about higher freq.
More of the mysteries of propagation ... I think
many hams know very little about the vagaries
and effects of propagation -- and I am one who
needs to learn more about this aspect of radio.
Hams often talk about take-off pattern, yet blithely
ignore what might be happening to the signal after
it leaves the the back yard.
About S meter accuracy. You either hear them or you dont. If you can hear
them and work them, it dont make any difference what the S meter reads.
I worked a lot of DX on my Omni C that did not move the S meter needle, but
they made it into the log.
I thought there was a school of thought that
based the signal strength component of signal
reports on S-meter readings - in which case it would
matter to them whether or not S-meters were
1) accurate, and 2) consistent between rigs.
If so, then I think this would be a worthy topic
for beating to death. ;-)
