It seems that we can draw some conclusions from these
assumptions.

Vf*If*cos(0) = forward joules/sec

What is this "we" business? That is your conclusion

What is the cos(0) term for Cecil? Are you implying that the phase angle of
Zo is 0? That isn't true in the general case, it is true ONLY for lossless
or distortionless lines.
