Cherry's Index

Evidence-of-quality score, not a cup score. Methodology

49

Confident

Confidence48% coverage / 3 of 7 signals

Enough independent signal to score at face value; no shrinkage applied.

How confidence affects the score

Coverage measures signal availability, not cup quality. Missing sources are dropped, remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 0% so one thin signal cannot carry the score on its own.
