Proof

Proof: what our models actually scored

Everyone publishes their wins. These are the working notes — including a validation failure that would have shipped if we had not held data back.

Error on unseen data — the only accuracy number that counts
Fit on data it could see4.85%
Predicting 3 months it never saw3.87%
Our 10% ceiling — above this we do not ship, and you get your money backReal client model, 14 markets, 22 channels

Predicting months it never saw came in below the fit on months it did. That is the signature of a model that learned the business instead of memorizing its history.
