The description of his test setup is on his web page.
Did he use standing-wave current to try to measure the
delay through a loading-coil? Yes, it is obvious that
he did.


From what is written there it's not possible to know exactly what he
measured. Why don't you take some measurements yourself if you feel
that strongly about it? And please stop shouting at cars. :-)

The standing-
wave current phase shift through a coil bears no
relationship to the delay through a coil.


I have no idea what 'standing wave current phase shift' is supposed to
mean. Standing waves obviously don't propagate, so naturally there
wouldn't be a propagation delay associated with them. Hopefully you
understand that radiating RF currents don't stand, they travel [1].

[1] Contrary to unpopular misconception, the reflected wave doesn't
actually affect the forward wave. Forward and reflected currents both
radiate equally well at every point along a radiator. What we see is
the net result of the fields that are present.
