The transmission coefficient equals (2*Z2)/(Z2-Z1). If
Z2 is large compared to Z1, the transmitted voltage can
be large compared to the incident voltage.
Yes indeed. And since this happens when the impedance
increases, energy can be conserved.
Agreed. Extremely important point.
But the discussion was about reflected voltage and how using
the generally accepted formula can result in the reflected
voltage exceeding the incident voltage. Converting this
voltage to power would result in a greater reflected power
than incident which would seem to violate conservation of
energy. Perhaps this would be an interesting place for
you to apply your energy analysis?

Someone seems to understand the gist...
