call them "unaware presumptions." WHAT presumptions are they?

The presumption is that a directional coupler directly samples power,
when in fact it doesn't. It samples voltage and current separately.

Hi Ian,

A Directional Coupler consists of two transmission lines.
Transmission Lines are the media through which B/H waves migrate
inexorably fixed together. The premise (which you alone bring as a
clouded presumption) that the Bruene bridge somehow works with
independence from this is simply a convenience in discussing its
operation, a convention of discussion at best and not a reality.
