You've probably hit the nail right on the head there,
Tom. If your results agree with Roy's then you were
again more than likely measuring standing-wave current
and therefore gained nothing by making those measurements.

How do you explain a well-designed coil exhibiting a
measured delay of 15.6 nS at 16 MHz and a measured
delay of 3 nS at 4 MHz? Don't you realize that is an
impossibility according to the laws of physics? If
the coil is well-designed at 16 MHz, it would also
be well-designed at 4 MHz and exhibit very close
to the same delay at both of those frequencies.
Do you really think the delay changed by 81% between
those two frequencies?

Build yourself an SWR meter calibrated for the Z0
of that coil. Measure the SWR in your coil circuit.
I'll bet it will be nearly infinite. Seems you are
guilty of presupposing the proof again.
