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 | HOU | Why |
|---|---|---|---|
| Team rating | 1500 | 1498 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +12 | +5 | CHW: Sean Burke: team allows 0.60 fewer runs than with its usual starter (≈10 weighted starts) · HOU: Hunter Brown: team allows 0.25 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | HOU +9 Elo | HOU 51.3% | |
| Market-implied ratings | HOU 57.8% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | HOU 56.9% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | HOU 58.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
