Cherry's Index

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

63

Sparse signal

Confidence15% coverage / 2 of 7 signals

Score is heavily shrunk toward 50; treat as a placeholder until more sources arrive.

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 63% so one thin signal cannot carry the score on its own.
