I know exactly what you mean and I think you're dead on, especially about the sections becoming progressively more sensitive. One thing that hasn't really been covered though is the SPEED of the cycle. I've noticed that the peeling has sped up in terms of how long it takes to reach the end of the cycle as I've progressed. This seems contrary to some of what other people have posted (then again, I don't know if any of them were actually cured), but I think it may all be related to what triggered it on a person to person basis.
