A. had no offset whereas B. had a humoungeous offset. It was just an attempt to show Lu that phase angles can be greater or less than 90-degree.

My current belief is that
Gyroscopic precession explains the activity inside the flapping/teetering hinges.
Aerodynamic precession, including non-gyroscopic dynamics, explains the activity outside the flapping/teetering hinges.
Therefor;
Gyroscopic precession has nothing to do with teetering rotors.
Gyroscopic precession has next to nothing to do with all other rotors.
