Because all existing definitions are too fallible. We have no idea who has "PEM" unless they had appropriate testing, which for now is the 2 day CPET protocol. The definitions are flawed. All of them. Of course some are more flawed than others.I'm not exactly clear on why they would find 2 groups of people when it seems by definition there should only be one to begin with.
For example, if someone has exercise intolerance then they might be diagnosed with PEM, even though they shouldn't be. Others might describe their condition as PEM but it is something else. Without a test we cannot be sure.
