Evidence-of-quality score, not a cup score. Methodology
46
Preliminary
Confidence2 of 7 signals on file
Score is partially shrunk toward a neutral 50; read directionally until more source families land.
How confidence affects the score
Coverage measures signal availability, not cup quality. This coffee has 30% 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 25% so one thin signal cannot carry the score on its own.
The math on file: renormalized base 44.6 shrunk to 45.9 = 46.
