I'm thinking there are at least two limits coming into play. First is the
efficiency/design of the regulator in the SM, and the second is the current
limit of the power supply

Load impedance changes constantly while booting. It levels out after booted
up. The real data I posted yesterday I did exactly that. I added 8 ohms and
it quit working down in the 15 volt range. It was below 11 volts on the SM.
So 6 watts/11 volts = .545 ohms

So, here's my question (which I would play with on the bench if I was
at home)
Take a radio (such as a 100 series cambium) that is known to run down
to below 12V
Put 29Vdc into the circuit. Add series resistance

Put 29Vdc into the circuit. Add series resistance until the sqrt(4RP) term
reaches zero. This should be about 14.5vdc.

This is what I was looking for when I started this quest.
The formula is so simplistic
