(For what it’s worth, the mushed average appears clearer to me from a user standpoint than the Starsort, where without the statistics explanation Dan gave above, I’m kind of left going “how come HeroFall at 2485 ratings is higher on Top Rated than Werewolves Haven Rising with 7068”, what’s up with the way it’s being calculated".)
