Methodology
How the CFB Index actually works — sources, tiers, sample-size rules, and which pipelines ran most recently.
Fan Intelligence methodology
The full doctrine behind every number on a player or team page: the
four-tier confidence model (A / B / C / D), the effective-sample-size
floor, the cohort weight matrix, known coverage gaps, the glossary
backing every ? popover, and the source catalog grouped
by tier.
Calibration track record
Our public confusion matrix. Every prediction we publish is logged before the outcome is known, then graded weekly. See how often our calls were right — broken down by model, prediction kind, and confidence band — including where our high-confidence calls missed.
Data source freshness
Last successful run per registered source, with status and rows inserted. Refreshed automatically each week. Useful for diagnosing why a cohort cell is showing “Awaiting Signal” — usually it’s an ingest that hasn’t run, not a real data gap.
