Or the velocity factor of the traveling waves can be measured by the

I agree, one can use knowledge and indirect methods. That's
exactly what I do and have been recommending. You and I seem
to be in agreement.

I am not sure we have the exact same thoughts, but I think there are
areas of agreement.

The real revelation for me, from this discussion is how the concept of
"phase" takes a dimensional jump (from time to position) when you
change from taking about a traveling wave to the standing wave that
results from the superposition of a pair of oppositely traveling waves
of the same frequency.
