What it measures and how

Use overall_score_100, assessing plot and expression across eight chapters. Judge preferences are disclosed as a limitation.

How this evidence is used

Counts toward ranking; the two writing benchmarks share 6% in total. More tasks or models do not increase their weight.

Benchmark results

Fixed rules select one representative configuration per public model. Anonymous test models are omitted. Original source ranks are retained, with up to 30 models per benchmark.
