I always thought tier lists made the most sense if you just consider them a ranking list based on matchups weighed with the proportion of characters within a given tournament or meta.
The general formula to calculate the weighed matchup average for any given character would be:
weighed matchup average of char x = (percentage of char 1 used in a tournament)*(matchup between x and char 1) + (percentage of char 2 used in a tournament)*(matchup between x and char 2) + ... + (percentage of char n used in a tournament)*(matchup between x and char n)
percentage of char n used in a tournament is just empirical data. Even matchups can be empirical data as well if we treat it as the percentage of matches won by x over n instead of theorycrafting like most people treat it.
I just hate how vibe based tier lists are. And I wouldn't mind it being vibe based except people still treat them with a veneer of something that's quantifiable.
