Knock yourself out if you want to try and change everyone's detailed and satisfactory understanding of how a rotor system behaves - you will probably find that no-one cares or listens. There have been many very clever people working in the design and construction of helicopters for many years and you think you know better - crack on and prove it
AnFI, read awblains comment about max pitch being the point of max lift and you will see he is wrong and that is why I emphasised the AoA (which is max at the same point as max rate of pitch change) as being the main issue.
