There you go again, Jim, trying to set up a straw man.
I do NOT treat powers as anything except scalars.


It was curious that someone would qualify his statement that way to
begin with - "treated as scalars". What's that supposed to imply if
not that there are other ways to treat "powers" sic.

Is there, or is there NOT a cosine term in the interference equation?
How can a scalar have a PHASE ANGLE, and how can the cosine term
possibly apply to anything OTHER than the terms used IN THE EQUATION?!!

I wonder if you'd care to comment on the other mathematical techniques
you introduced to the group this week:

Subtracting power that isn't somewhere else from a number that's
apparently higher than it should be in order to get the right answer,
and averaging power with zero as a means for reducing an excessively
large number by a factor of two in order for the answer to come out
right. I'm still trying to parse how neglecting units makes it ok to
use equations as you see fit. $100 + $100 + 2*SQRT($100*$100) = $400
(The third term represents the amount of money that isn't somewhere
else and should therefore be mine.) ;-)
