Orval, I can't thank you enough (missing energy found!). That was the
missing piece, even though it is so obvious after you point it out. I
haven't seen that part explained or referred to in all of the usual
discussions.

Thank you very much.

In the case of descending flight, gravity is supplying some of the power
required to maintain flight. With wings level, you are at 1.0 g whether
climbing, level or descending. The same rules apply to turning flight.
