Thanks Cecil. I wanted to be sure where you were at now.
We still disagree about several important points.
"The unwillingness of the "gurus" to answer specific
technical questions is pretty disappointing."

You said you could use the lumped-circuit model to explain
how the current at the top of the coil could be greater
than the current at the bottom of the coil as it is
at the bottom of the page at:

If you are technically correct, why are you so technically
silent on the subject? Does the emperor have no clothes?
At least a dozen of my technical questions have gone
unanswered by being ignored. Lot's of readers have
noticed and commented in emails to me.
If you will repeat your measurements with 1/4WL added
to the top of the base-loaded mobile antenna, you will
start to understand the physics involved. The current
taper through a coil depends upon where in the standing
wave environment that the coil is installed.
The lumped-circuit analysis fails for the typical
75m amateur radio mobile antenna.
