Meh, I respect the work you put into it. I'm not arguing any numbers or formulas you are using.
But just by the eye test and history I put Dan Henderson higher and Rampage lower. Also not sure why Ken Shamrock makes it but Royce doesn't?
Because it's Frank who should be much higher. The biggest issue I would have is this is a GOAT list not p4p. Tito doesn't belong on a p4p list, Tito is sub.500 against real LHW's.
As for who is the p4p greatest...I think Matt Hughes and his wins over BJ and GSP rank him as #1. You say Anderson Silva is the best p4p but look at the list he's only beaten 1 other guy (Dan Henderson) on the list.
I think p4p I would go
