Well, let's try one more time and see. Assuming a 50 ohm
environment (by definition) in the following example, what
will an ideal 50 ohm directional wattmeter indicate at
point 'x' for forward power (Pf1) and reverse power (Pr1)?

It's a simple question with easily calculated and
quantifiable answers.
Your circuit is incomplete. The circuit parameters are not fully defined.
Is this the same circuit that you wish to analyze?

What is the impedance of the voltage delivered from Vs before the wave encounters the resistor Rs?
What reflection characteristics should we assume for the voltage source Vs?
