I suspect that the sort of precision with which one can measure signal

varying ground conditions, mean that it would be hard to know if the
signal level resulted from, say, one, five or fifty percent of the
transmitted power.

So I suspect your question has never been answered.

But somebody must have done the research, somewhere...

Thoroughly researched for well over 100 years but you refuse to read
the research which says your question in the form it is being asked
is meaningless.

An opportunity for some collaborative research between local amateurs?

No-one wants to run verticals...too difficult....

Vertical antennas have little to nothing to do with the essence of
your question.
