You claim that W7EL measured the phase shift of standing wave current.
He of course made no such claim. So yes, I need you to explain how it
is possible for someone do measure a "current" that does not flow. This
should be good.

I measured current (of which the definition is well understood except
apparently by Cecil), and took a lot of care to do it right. Cecil
doesn't like the result, so he's created an imaginary quantity he calls
"standing wave current" as an attempt to invalidate the results and
promote his imaginative theories. Since it's wholly his creation, its
properties are free to be modified as the immediate argument requires.

As I, Jim, other posters, and all good texts have explained, a standing
wave describes the amplitude envelope of a voltage or current, as a
function of position, which results from interference between traveling
waves. There's no such thing as "standing wave current". You'll find no
references to this fictitious entity in any electromagnetics text.
