A lot on 75m. Not much on 12m.

Or lets go one
better...What would be a likely "worse case" scenario?

The worse case I can think of is a short center-loaded whip
on 160m. :-) The coil is almost all of the necessary 1/4WL.

Will this vary from antenna to antenna? I would think so.

Of course. It is all capable of being calculated.

Is it your opinion that the modeling
we now see with these antennas and coils is quite flawed?

The antenna current reported by EZNEC is inaccurate because of
simplified assumptions. EZNEC assumes that the current doesn't
change through the single point inductive load. Therefore, EZNEC
cannot be used to prove that the current doesn't change.
