Cecil,
I guess I am a bit puzzled.
The bugcatcher example I sent you showed a phase shift of about 7
degrees at 4 MHz. The current at the top of the coil drops off to about
85% of the base current. I believe the delay computes to something
around 5 ns. That does not seem like a HUGE delay for a coil that
contains nearly 40 feet of wire.
I presume you can now duplicate and verify these results, since we have
not heard any contrary information. That coil is real close in design to
a genuine Texas Bugcatcher #680 from Henry Allen.
Absolutely no one around RRAA clings to a rigid lumped component model,
except your straw man. The distinction is that most people treat this
non-ideality as a perturbation. You seem to want to elevate it to the
status of realignment of the planets.
It has been explained over and over why real coils are not ideal. I am
sure you understand. I am not at all sure why you persist in carrying on
this rather pointless argument.
Actually Gene if you look at:

your EZNEC model's current agrees with similar coils in antennas I
measured.
I expect Cecil will ignore what you sent him, or announce it supports
his conclusions by editing the data.
