So I've always understood that overexertion can lead to permanent detoriation in every ME/CFS patient.
The problem for the medical profession is that we have no factual proof of this - for anyone. We can document symptoms and signs but saying what caused what is a different thing. It normally takes years of research to prove what causes what. We are all very unreliable about judging waht causes what so it has to be verified.
I think this is the basic problem with any classification based on such a concept.
