Gary's correct, but there do seem to be limitations, even when these
precautions are taken.  I followed exactly the procedure he describes with
my C-3 modeling, and while gain and pattern converged, the 15-meter
feedpoint numbers remained far from observed reality.  The only point I was
really trying to make is that it might be simpler and would probably be
more reliable in this case simply to install and try.
