Tom, I don't disagree with your point at all.  The ONLY thing I was trying 
to point out is that modeling is one useful tool, among many, that learning 
how to do it better is worthwhile, and that knowing the exact values others 
obtain with modeling .  I freely acknowledge (even insist) that to do it 
well means understanding the known weaknesses of the model, including 
imperfect modeling of ground media.  I suspect that this is more a problem 
with verticals than with horizontal antennas, and that NEC-based models 
seem to be biased against verticals.
