Just to point out that we don't have measurements of arrival angles at the
ionosphere proving the fields shown in a NEC far-field analysis, either.
Yet people seem to accept a NEC far-field pattern as gospel, even though
it does not accurately show the radiation launched by a monopole at
elevation angles below 10 degrees or so.
We have a lot of things we claim as fact, even though we don't supporting
data. Some border on magic.
That's why I A-B test things for several months before deciding anything.

I installed a 300 foot tower because I remembered how well a dipole at 300
feet worked at a BC station. I was sure, based on the DX contacts, the
dipole was a killer antenna for receiving and transmitting. Problem is when
I finally installed that wonderful antenna after all that work, my vertical
tied broadside to the dipole and badly beat the dipole off the dipole ends.
