Except that's not exactly correct.
Combat Power can only be roughly placed into tiers, and win rate is only particularly effective when it's done in a round robin style, so everyone has a chance to face everyone else.
Without that, win rates aren't nearly as concrete. For an RP Sagisō > Furījia, and Baiyan > Sagisō does not guarantee Baiyan > Furījia.
Don't pay that much attention to statistics, they're data, and as all data, they're inflexible and not suited to representing a varied and frequently shifting state of being.
and this is precisely my point. You're thinking objectively, and RPs are subjective.
