NFL Model Validation & Track Record
A prediction model is only as credible as its evidence. This page explains how Alphr's NFL model is validated, and how its 2026 track record is kept genuinely verifiable rather than cherry-picked.
New for 2026
Alphr's NFL coverage is launching now. Rather than advertise a strike rate it has not yet earned, every NFL tip is recorded before kickoff and graded afterwards, so the published accuracy and ROI build week by week from real, out-of-sample games.
Temporal Train / Validation / Test Splits
The model trains on historical NFL seasons, tunes on a held-out validation season, and is evaluated on a separate, more recent test season it never saw during training. This temporal split mirrors how the model is used in production, always predicting the future from the past.
Anti-Leakage Feature Engineering
Every feature is computed using only information available before kickoff. Rolling form, ELO and head-to-head features use window functions that exclude the current game, so no future information can leak into a prediction.
Pre-Game Recording
Tips are timestamped and stored before each game starts. Because outcomes are graded after the fact and never edited, the published win/loss record cannot be retroactively improved, the definition of an honest track record.
