So why do you have to go to all that trouble when you want to measure

When one measures traveling wave energy, one
is measuring an average calculated scalar value
usually forward power minus reflected power or
RMS V*I in a dummy load resistor.

Sounds like "one" Cecil is shy of experimental horsepower. And for
"energy" yet. Another gejoken experiment where the energy of current
(known) and the energy of voltage (known) has the requirement of
finding the gejoken energy (unknown to Cecil, except as an abstraction
spread out over time and phaseless) squared? Some"one" isn't trying
very hard.

The question wasn't about energy squared. It wasn't about RMS (who
cares? Isn't there a scope sitting nearby?). It wasn't about a dummy
load resistor. But these objections do make a nice list of excuses. I
can well imagine that list will only get longer as the list of
experimental options shrinks into a cerebral vacuum.
