After trimming roughly the most extreme 10% of ratings on each side, the spread is no more than 1 point. The main body of votes keeps the game in almost the same place.
COMMUNITY TIER LIST
Every saved tier list, averaged into one collective diagnosis of gaming taste.
The robust spread is 1.01 to 2.10 points. The disagreement is visible, but most voters still place the game in roughly the same part of the tier list.
The robust spread is above 2.10 points, but there is no full split into two camps. The average is already smoothing over a real disagreement around the game.
The robust spread is above 3 points, with at least 15% of votes in both the high and low ends of the scale. At that point people are no longer arguing about placement — they are arguing whether the game is good at all.
