Every Aircraft Type Maintenance Manual has a procedure for calculating and checking for Autorotational RPM.
Stabilised at 1 g

As part of routine maintenance and checking for air worthiness....that Check is done using the approved procedure.
Stabilised at 1g

The Target RPM always falls within the authorized Power Off RPM Limits set forth by the Manufacturer of the Helicopter.
When stabilised at 1g

As I read your post quoted above.....I interpret it to say a properly rigged Helicopter will never stabilize Main Rotor RPM in a steady state Autorotation.
It will, but entry into autorotation is not a steady state. It may be that by the time steady state is reached, rrpm has fallen too far and the steady state becomes one of a brick.

Am I not understanding what you are trying to say?
Obviously not!
