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 | KC | DET | Why |
|---|---|---|---|
| Team rating | 1495 | 1516 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −2 | −7 | KC: Michael Lorenzen: team allows 0.09 more runs than with its usual starter (≈10 weighted starts) · DET: Reese Olson: team allows 0.33 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | DET +34 Elo | DET 54.8% | |
| Market-implied ratings | DET 54.6% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | DET 54.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | DET 59.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
