Starter identity IS a model input: each probable's rolling game score (exponentially weighted, 20-start half-life) is compared to his team's staff average and the difference enters the team's Elo at 3.0 points per game-score point (the SP adj column, so the effect is auditable per game). Rookies/thin history fall back to a shrunk staff rating; TBD uses the staff rating. Rest and travel add up to a few Elo points each. Win probability from Elo (+24 home advantage). Expected total is matchup-specific: each club's recent runs scored/allowed (exponentially weighted, ~20-game half-life, shrunk to league average) sets the run environment, and the Elo-implied margin is carved out of it. Expected runs are shown at one decimal; read them as averages, not a literal final score.
