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 45.0 shrunk to 49.4 + bonuses = 49.
