MD here - I'd disagree. Although I've heard the same take from many other phsyicisans! Anyone who has worked with the condition (I've had 100s of CFSers by now) knows it's a pretty distinct syndrome. The CFS push-crash cycle especially is quite distinct.

Isn't the push-crash cycle pretty common in people that don't have CFS also?

No, in that for people who are fully healthy, they don't have periods of avoiding exertion due to fatigue, which precedes the push in the push-crash cycle. People with well-balanced health and energy can certainly over-exert themselves, but it's not a common cyclical pattern for them characterized by the push happening when some recovery from fatigue occurs.
