I'm fairly sure that (forward power) - (reverse power) gives the correct
nett output power, before cable and antenna losses. I'd need to review
the maths to be sure. Most reflected power ends up re-re-reflected, as
additional forward power. A high SWR will giver reflected power almost
as high as forward power.

Case and point. On one of my antennas, on a frequency where the SWR is
high, the FWD power indicated on the external meter is 200 watts. No
way the radio is producing 200 watts. At the antenna matched frequency
the external meter indicates 100 watts.
