The stall you refer to would be on the retreating side, and to be honest I have not worked out the math to determine the percentage it would stall at, but there would be many factors---primarily forward speed.
No, I got that your point was about not freaking out. My point however, was simply, they say it stalls at 80, so why is it not stalling at 70?,...as I don't recall them mentioning that you must have forward speed to get low rpm rotor stall?
I will consult my texts then.
