Let me ask you this: how would you go about calculating the phase shown
on your Standing Wave Current graph, and what meaning if any does it
hold for you?


Kraus already did it for us. Note the relative phase
graph.

The phase shown on my Standing Wave Current graph is
the phase relative to the source phase. For a pure
standing wave on a 1/4WL wire, the standing wave current
phase is everywhere equal to the source current phase.
That's why it cannot be used to "measure" the delay
through a wire or through a coil.
