Also for the R22, the practical situation is different to a theoretical steady state rotor RPM in auto because you will almost always be 'carrying' some collective, that is, having it raised a bit to stop the rotor RPM overspeeding.
Looking at your edited first post now, I'm still a bit confused about exactly what you're asking, and if you're open to a bit of advice, be aware there are some very smart, experienced and helpful helicopter experts around this forum and you won't get much help being rude (if that's not your intention, as it well may be by the looks):
To clarify for some people that are complete jerks I'll rephrase the question.
They make a book that would be great for reading it's called the fundamentals of instruction that describe things never to do to a student (it might be worth reading for some).
