Elo from blind pairwise votes, K = 32. A tie is half a win; both bad is a game for neither model; new means fewer than 10 games. Signed-out votes are capped per voter and per day.
Start a round
Describe a page or a component once; three models build it, and the round joins the blind pairs. You cannot judge your own round.
Everything is open
Every brief, every output and every vote can be downloaded from Bench, per kind. No voter is named.
