What the backtests support These verdicts summarize the frozen 2024–2025 evaluation. They do not promote experimental forecasts into current recommendations. A single correct pick is not proof of a repeatable pattern.
One game
No single-game verdict 80% margin range: ±18.0 points; observed coverage 82.3%
A single upset or correct pick cannot tell us whether a forecast has a lasting edge. Judge frozen predictions over many games.
The range is calibrated from historical errors; it does not capture every roster or injury change.
Across games
Measured pooled edge over Elo Model − Elo Brier -0.0078; 95% block interval -0.0140 to -0.0018 (n=569)
Lower Brier is better. The paired interval stays below zero across the pooled held-out games.
This is a historical model comparison, not proof of an advantage on the next matchup.
Across seasons
Consistency still mixed 1 of 2 seasons have a model-favoring 95% interval versus Elo
2024: -0.0139 to 0.0042 · 2025: -0.0186 to -0.0024
Only the evaluated seasons are represented. More unseen seasons and model-change controls are needed before calling this durable.
Player to next season
New signal not established Candidate MAE 3.103 vs age plus production 3.098 (3009 player-seasons)
The candidate does not beat the strongest existing baseline on this point-error measure.
Inspected historical seasons and excluded rookie or thin-history cohorts limit any claim about next-season skill.
Historical market check
Market ahead on paired subset Model − market Brier 0.0107; 95% block interval 0.0040 to 0.0185
Positive values favor the historical market on games with matched odds.
Historical odds lack archived quote times. This is not evidence of a real-time or tradable edge.

272 scheduled games, 32 team outlooks, probability calibration, score errors and player-production experiments. Frozen preseason research; does not change public rankings.
Original capture date; opening or downloading does not refresh the source. Per-record timestamps take precedence. Definitions may describe unavailable inputs.
How to read and verify this data JSON bracket paths; [] means every array element. CSV uses concrete zero-based indices. Types are observed, not a promise that future fields cannot change. null is unavailable; empty array/object means an empty collection. Zero is preserved as a measured or supplied numeric value. Source-native units and scoring. Consult metric-definitions for formulas; ambiguous units remain unspecified, never inferred.
sha256 of UTF-8 JSON.stringify(data), excluding this envelope. Source receipt hashes remain inside data. CSV prefixes formula-looking text with an apostrophe; numeric signs are preserved. JSON keeps original strings.

Published observations, approved source-labeled aggregates, research and definitions are provided within each dataset's stated scope. Read each record's source, period, scoring and availability. Research visibility does not promote a model into public rankings. Missing means unavailable, never zero. No account records or provider write access.
