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.
