Cherrybook Index (CBI)

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

54

Sparse signal

Confidence1 of 7 signals on file

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. This coffee has 5% of the signal universe on file. Missing sources are dropped, remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 88% so one thin signal cannot carry the score on its own.

The math on file: renormalized base 80.0 shrunk to 53.8 = 54.

Missing: SCA grade, Coffee Review, Reddit sentiment, YouTube reviews, On-shop ratings, Cherrybook ratings
