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 | KC | Why |
|---|---|---|---|
| Team rating | 1551 | 1466 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +14 | −16 | CHC: Clay Holmes: team allows 0.72 fewer runs than with its usual starter (≈10 weighted starts) · KC: Seth Lugo: team allows 0.82 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | CHC +97 Elo | CHC 63.7% | |
| Market-implied ratings | CHC 61.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CHC 61.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CHC 58.7% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
