The existing neutral-field rating prevents a single noisy opener from producing a fake transformation.
The 4M model room
SHOW
THE WORK.
A useful model should be explainable, versioned and judged against results it did not already know. CollegeFootballData supplies the evidence layer; the calculation and editorial judgment remain ours.
The starting position
A prior that can move—but cannot panic.
The published 4M 138 remains the preseason baseline until the CFBD edition clears its first audit. Every refresh creates a new database snapshot; no historical edition is silently overwritten.
Multiple opponent-adjusted and predictive views reduce dependence on one outside model.
Player usage and position value distinguish proven transfers from raw transaction volume.
CORE, adjusted EPA, success rate, explosiveness and special teams earn more influence as 2026 snaps accumulate.
Neutral-field rating differences, a 2.4-point home field and completed results produce expected regular-season wins.
Inputs, coverage, model version and output are stored together so every public claim can be reconstructed.
Daily operating rhythm
Update the data daily. Move the rating only when the evidence earns it.
A timestamped edition keeps the public board honest and prevents silent revisions after a result.
Return to the 4M 138 ↗- Reconcile
Final scores, play-by-play, advanced box scores, participation and corrected game records.
- Refresh
Opponent-adjusted team metrics, roster transactions, injuries, depth charts and schedule data.
- Re-estimate
Run the weekly model after the full slate is final; preserve the previous version for an audit trail.
- Price the matchup
Refresh market consensus and weather, then issue a final number after availability reports.
The public scorecard
Accuracy has more than one definition.
Average absolute error between projected and actual scoring margin.
Whether a stated 60% outcome occurs near 60% over a meaningful sample.
Rewards accurate probabilities and punishes unjustified confidence.
Whether published positions consistently beat the eventual consensus close.
Tracked at the exact posted number and price, never a later favorable line.
Every weekly release archived so results cannot be rewritten after kickoff.
