How Cherry’s Index is calculatedavg coverage 33% · limited data

Coverage is below 50%. Most of this roaster’s lots are scored off roaster-level signals (Reddit + YouTube) without per-lot SCA grades, Coffee Review entries, or published buyer reviews. With limited signal, scores are also pulled toward a neutral 50 baseline by the Cherry’s Index methodology, so lots can read flatter than the actual cup quality differences between them. The avg Cherry’s Index reflects general reputation more than per-lot quality.
