standing wave current phase shift - whatever that is.

It's not my take, Jim, it is EZNEC's take. EZNEC
reports current on a standing-wave antenna that
closely matches the standing wave equations for
current whose phase cannot be used to measure
delay through a wire or through a loading coil.

Both w7el and w8ji used the current
on a standing wave antenna to measure phase shift
and predictably, there was negligible phase shift.
They erroneously attributed the lack of phase
shift with a lack of delay, i.e. they assumed the
proof - a well known logical fallacy.

There is no relationship between phase shift and
delay in the current on standing wave antennas
either through the wire or through a loading coil.
