The PACE recovery paper allows someone to be deemed recovered, even if they report their physical function to still be atrociously bad, worse in fact than to be to be allowed onto the trial in the first place. MS argues, I believe, that such a person could only be deemed recovered if their other measures were good enough to 'counteract' the bad physical function, so their blended overall result still came out as a 'pass'. Most other people see that the final blend is by no means all that counts - if something as fundamental as physical function is still atrocious (worse, even, than they could have been allowed onto the trial with), then no-way-no-how can the person be considered recovered.
