How the number is built
Elo inputs in rating points (higher favors that team; 25–28 Elo is about a point of spread in football and basketball), then how the pieces combine.
| Factor | CHC | DET | Why |
|---|---|---|---|
| Team rating | 1547 | 1537 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +6 | −21 | CHC: Jameson Taillon: team allows 0.31 fewer runs than with its usual starter (≈10 weighted starts) · DET: Tyler Holton: team allows 1.03 more runs than with its usual starter (≈7 weighted starts) |
| Elo ratings | CHC +19 Elo | CHC 52.7% | |
| Market-implied ratings | DET 50.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | DET 50.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CHC 52.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
