	It will be interesting to see what the "big boys" say, but those rules
sound very arbitrary, and perhaps even nonsensical.  I suspect that, in
the case you mention, you would have been at least as well off leaving
the extra four inches on the coil.  As long as you have everything tuned
OK, the results should be fine.
