Slow rotor, when I was at school it was called the "wave /particle duality" and simply meant that both concepts could be applied under different circumstances, not that either was correct in isolation.
SASless, I think that in reality, the concepts being discussed on that other forum, have always been known by those who need to (the designers and test personnel) but they are too complex to be taught in basic flight training. Some people have enough trouble dealing with electrical AC theory- how would you expect them to cope with the aerodynamics of the rotor? Do they really need to know anyway?
If you can impart a theory that seems to work, which is relatively simple to understand, then so be it. At least the pilots will have some understanding of how to treat their aircraft safely without chopping bits off; that' the important bit!
