I like power (known) per unit area of a sphere (set); it is direct and easy
to do. Once you've figured isotropic, you can account for other variables.
Might even be amenable for adjustment for near field impedances. Works well
on napkins for all kinds of stuff. I used it the the other day for a link
budget for passive satellite scattering. (Lots of assumptions though.)

Remember, in the "good old days" 20 percent was close enough. What's
that... +/- 1 dB?
