That is STILL 3 groups, and ignores the votes for the "At" group. When broken into 2 groups (which includes the "At" votes) 150 wins.
Fine, let's include the at votes:
At 150: Less: 31, Same or higher: 40
At 120: Less: 29, Same or higher: 42.
At 100: Less: 3, Same or higher: 68.
Both 120+ and 100+ have more votes than 150. How does 150 win in this scenario?
Wouldn't 100 win in that case? I've already made this point previously.
Edit: And it's not three groups, it's two: higher and lower. I'm ignoring the sample point I'm on. But note: "votes for even larger or smaller sizes than the current size should be aggregated" names three groups: larger, smaller, current.
