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 | MIA | CHC | Why |
|---|---|---|---|
| Team rating | 1446 | 1535 | Elo entering the game; 1500 is league average |

| Starting pitchers | +23 | −3 | MIA: Ryan Weathers: team allows 1.14 fewer runs than with its usual starter (≈9 weighted starts) · CHC: Jameson Taillon: team allows 0.13 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | CHC +82 Elo | CHC 61.6% | |
| Market-implied ratings | CHC 63.3% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CHC 63.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CHC 65.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
