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

[CFH]

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.

None of the fights that propelled Pacquiao to the top of most peoples P4P rankings were fought at a catchweight.
