Evidence-of-quality score, not a cup score. Methodology
51
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 40.0 shrunk to 48.8 + bonuses = 51.
