How the values are distributed

Across the 20 numeric entries in this window the median is 1532 and the mean is 1519, so the typical entry sits 130 below the leader. The window spans 1330 to 1662.

21323324
8 equal buckets between the smallest (1330) and largest (1662) value; numbers under bars are entry counts.

10 of 20 entries are at or above the median, and the top three hold 16% of the combined value — read it against the metric below, since a higher number is not "better" for every dataset.

Creators in this ranking

8 creators appear in this window; the three most-represented hold 70% of the entries.

Metric reference

This ranking carries the metrics aaBriefcaseElo_lower, aaBriefcaseElo_mid, aaBriefcaseElo_upper from the AA-Briefcase Elo dataset in the tab::eval-briefcase family. Units and the direction of "better" are not declared by the source dataset, so AI Battle does not invent them: values are shown exactly as published, and the ordering is the source dataset's own.

How this ranking is built

Rebuilt on from the public dataset AA-Briefcase Elo (family tab::eval-briefcase). The source lists 20 entries and all 20 are shown here. AI Battle requests the dataset's rows, keeps the ordering the source publishes, and computes only the statistics on this page: median, mean, spread, the #1–#2 gap, the creator breakdown and the raw-data file. Nothing on this page is generated text about the entries — the numbers come from the source.

Refresh cadence: every deploy re-pulls the dataset, so this page tracks the source's own update cycle. Corrections: see the methodology page.
