How the Cherrybook Index is calculated hereaverage 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.

Base components are renormalized over whatever signals are available for each lot. SCA + Coffee Review are capped at 40% combined to keep the cupping story from dominating. Bonuses (accolades, awards, editorial coverage) and freshness decay are applied on top.
