I am more than somewhat familiar with that flow chart and training model, having been involved in the early versions of it well over a decade ago
Ditto.
My untraining comment related to negative habit pattern transfer from rotorcraft as opposed to from multi engine airplanes for already experienced fleet aviators entering the V-22. Many found that surprising as it was opposite some expectations. Just an observation, and one that is no longer based on my own day-to-day experiences. In my time training some of the students in the rotorcraft part of the pipeline (probably about the same time you were involved) the balance of multi and rotor seemed to be a moving target.
