Determining ability potency, in what??. Layers or hax weakness, which a subjective term, you say it is layered hax, i can say otherwise. Anyway, back the matter, how to index???, slap some number on the profile, which again cam be subjective.
Not denying some verse establish some kind of mechanic, but again if said verse establish it, we can safely indexing on profile, like Yogiri's Resistance Negation if i read his profile correctly. However, with verse that not establish anything, how to indexing???. Like i said before people could say this weakness that weakness, not layers, since this term is very subjective
