Sparse signal

Confidence23% coverage / 2 of 7 signals

Score is heavily shrunk toward 50; treat as a placeholder until more sources arrive. Coverage is signal availability, not cup quality; missing sources are dropped, the remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 43% so a single thin signal can’t carry the score on its own.
