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 | WSH | SD | Why |

| Elo ratings | SD +76 Elo | SD 60.8% | |
| Market-implied ratings | SD 57.6% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SD 58.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SD 56.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
