Wrong yet again. I never said it would not approach 100% duty cycle, and that's not what's
meant by "continuous load".
If the AC unit runs at 26 FLA for 3 hours and 1 minute on the hottest
day of the year, it is over 80% and "continuous" by code, so the wire
needs to be derated to 80%., meaning it needs a larger cable.

Are you simply not paying attention here. The 80% does not apply here
at all. It is already computed in the minimum circuit ampacity.
Continuous load doesn't apply to motor loads anyway since the
conductors are already sized to 125% of FLA.

And none of us knows enough about this "mythical beast" to know why it
is specified to be connected to a 50 amp breaker by AWG6 cable.

It's all conjecture at this point - your conjecture and mine equally
valid until more real information is provided.
