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 | 1410 | 1506 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −18 | +18 | CHW: Chris Flexen: team allows 0.91 more runs than with its usual starter (≈9 weighted starts) · CHC: Shota Imanaga: team allows 0.88 fewer runs than with its usual starter (≈7 weighted starts) |
| Elo ratings | CHC +150 Elo | CHC 70.3% | |
| Market-implied ratings | CHC 73.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CHC 73.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CHC 72.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
