Can one really be ranked P4P when you demand catch weights?

[Taeth]

Just wondering, because they have manny number one, but most of the time the fighters that have been ranked number 1 have gone to other's divisions and beaten them. RJJ, PERNELL, FLOYD, SHANE. Not once did either of them demand a catch weight.

Two things
1) Floyd, RJJ, Pernell, and Shane never went up as many weightclasses as Manny has, and to this point Manny hasn't foughten anyone at a catch weight.
