Why averages can mislead
Random subsets can estimate full scores well on average while occasionally producing a large error. The paper studies that tail risk across benchmarks.

What is available
The repository includes prompt and score data and a CPU-based experiment runner. Its recipe uses five probe models and 128 candidate subsets. No model download is needed for the bundled score-matrix experiment.

Where the evidence stops
Sources read; code and statistical results were not reproduced. A representative subset for one collection of models may not remain representative after distribution changes.
