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 | CHW | CHC | Why |
|---|---|---|---|
| Team rating | 1411 | 1533 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +10 | 0 | CHW: Shane Smith: team allows 0.51 fewer runs than with its usual starter (≈6 weighted starts) · CHC: Cade Horton (no track record yet) |
| Elo ratings | CHC +129 Elo | CHC 67.8% | |
| Market-implied ratings | CHC 68.1% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CHC 68.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CHC 67.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
