How Cherrybook Index is calculatedavg coverage 5% · limited data

Coverage is below 50%. No Reddit or YouTube roaster-level signal is on file. Per-lot evidence from SCA grades, Coffee Review entries, and public on-shop product ratings is limited across the catalog. With limited signal, scores are also pulled toward a neutral 50 baseline by the Cherrybook Index methodology, so lots can read flatter than the actual cup quality differences between them. The average Cherrybook Index therefore reflects the limited per-lot evidence plus the methodology's neutral baseline.
