Validity — a filter, not a chooser

AUC 0.753 (95% CI 0.713–0.794), fused ranking. Bottom-decile bars are red when below the base accept rate (31.1%). “Not accepted” = rejected + withdrawn

A rejected paper's median percentile is far below an accepted one's — but the distributions overlap at the top, which is why we filter rather than choose.

Reliability — internal precision

Fraction of observed θ spread that exceeds estimation noise, within each judge's own fit. NOTE: precise ratings are not necessarily correct ratings — a random tournament is internally precise too. Cross-judge agreement is the real validity evidence.

Convergence

Spearman ρ of each round's ranking against the final ranking, and mean absolute percentile change (averaged across both judges' runs). Stable for filtering by round ~4; boundary refinement through round 7.

Judge agreement & noise scale

Fitted noise scale ŝ = 0.31; cross-judge agreement 74%. A θ gap of 0.5 ⇒ the better paper wins ≈ 83% of comparisons.

Cross-band τ stays high while Swiss τ collapses: batches of similar-quality papers are genuinely harder to rank — that's judge noise at the boundary, not judge failure.
