Our method
- We simulate the final margin 40,000 times from our team ratings (Elo, fitted walk-forward) and the ESPN injury report.
- The win chance is the share of those simulations each team wins.
- When the market has a price (Polymarket), it gets 85% of the say and our ratings the rest: over ten seasons the market was the most accurate single input, and that mix was as accurate as anything we tested.
- Preseason game: starters play about half the minutes, so we halve the expected margin and widen the range. It's graded like any other game and marked preseason.
