Yes, the autorotation is as if the rotor was at the helicopter base! They are switched off below ~5kph wind, so no useful power generation.
Proven energy offer teetering rotors, which behave more like a heli autorotating. They actually use flapback to align on the wind, so rotor always downwind of mast.
This does beg the question: Any difference between autos in teetering and rigid?

So 1g hover about +7 to 8 degrees @75% span (assuming max 3g margin).
