Each score averages the model's last 3 comparable sweeps of every scenario and language (same rubric and judge panel). The rank range is a 90% bootstrap interval over those sweeps: models whose ranges overlap are not reliably ordered. With only 2–3 sweeps per slot it likely understates the true spread.

† Only one sweep so far, so the range can't reflect this model's own run-to-run variation.

Superscript n/7: scored on only the dimensions with data, weights renormalised. Not directly comparable with fully scored models.
