Interesting formula, however, not entirely accurate. Normally, these lists go off things such as tournament results, character usage, agreed upon potential, consistency, & Match Ups against others. More accurate variables would be kill consistency, recovery, survivability, slipperiness (ability to escape combos), gimp consistency for the matter.
How you see someone like Rayman, Eryu, Auraless Lucario or Link at S tier last version is becuase they had such jank amounts of those, Dominant Stage Control, Killing, Spam you could get away with & nullifies the entire cast because they do so effortlessly & the general cast has problems against their assets (Rayman Aerial control/framedata & down b, Eryu aerial Hadouken spam controlling the stage & versatile moveset, Link's BS base kb on all his moves & low endlag with his large range & no problem killing, and Lucario being all around n just being able to kill you with f smash & aura spehre spam at 60% minimum)
Ontop of that, they just didn't die & always lived long, could recover at will & couldn't be edgeguarded, had decent speed, & had a counter for most situations if not all, or generally plentiful of strong options that outshined the rest.
