If you think that's what I said, you are suffering from delusions.
*All* of my power components exist at a stationary point or plane.
The two components associated with wave cancellation exist at the match
*point*. "Reflected power" is the reflected energy flow per unit time
measured at a point by a stationary directional wattmeter. "Forward
power" is the forward energy flow per unit time measured at a point
by a stationary directional wattmeter.

Power components do not interfere. It is the E-fields and H-fields
that do the interferring. However, given the interference of two
coherent waves traveling in the same direction, the following
power equation is valid.

Ptotal = P1 + P2 + 2*sqrt(P1*P2)cos(phi)

where phi is the phase angle between the two E-fields. The last
term in that equation is well known as the "interference term".
If cos(phi) is negative, the interference is destructive. If
cos(phi) is positive, the interference is constructive. If an
additional source of energy is not present at the interference
point, the destructive interference must equal the constructive
interference to satisfy the conservation of energy principle.

Like I said before, the only disagreement that we have left is
whether dt is zero or infinitessimally small. Your straw men
are just straw men designed to mislead the uninitiated.

Note that Richard Clark is NOT using the above power equation
and is instead trying to superpose powers which is an invalid
practice. That's why he's calculating the wrong values.
