You've described a standing wave, but haven't defined any special kind
of current known as "standing wave current".

"Standing wave current" is the current that exists in standing-
wave antennas and stubs. It's phase is constant and cannot
be used to measure phase-shift/delay. EZNEC agrees.

Here is Kraus' graph of standing wave current.

This is a graph of the currents you used for your measurements.
Note the virtually unchanging phase.

For the record, I measured some currents in a wire on both sides of an
inductor at the base of an antenna a couple of years ago and posted the
results here. One of the things I measured, with some care, was the
phase angle between those currents. I didn't "mistakenly" measure
"standing wave current".

EZNEC says that the phase angles of the currents you measured
are unchanging. An unchanging phase is useless for measuring
phase shifts.

You'll have to run that one by Cecil. He's said many times that
traveling waves bounce off each other when they meet.

That's just part of your Big Lie. Traveling waves
superpose. They do NOT "bounce off each other".
