My ethical standards will not allow me to lie about
technical facts in evidence. You cannot bully me
into doing so.

When the average interference is zero, all of the
average reflected energy is dissipated in the source
resistor. It is true for all examples of Fig. 1-1.
You have not presented even one example where
that is not a true statement.

But all you have demonstrated is that the imputed
average power in the reflected wave is *numerically
equal* to the average increase in the dissipation
of the source resistor. Which is good, as long as
that is all you claim. Which it some times seems
to be, especially when you qualify with "interference
is zero".

Finer grained analysis shows that the imputed
energy (not average) in the reflected wave is not
dissipated in the source resistor. The trouble
is, sometimes you agree with this (when you
invoke that interference is present), but other
times you don't (see your response to the opening
paragraph). It is this flip-flop that makes your
actual position difficult to discern.
