All costs are tenure-bounded, season to date, and shown as a season total plus a per-game rate (R/G). Lower is better. The categories aren't summed into a total — lineup, bunts and IBBs cover every game while reliever selection covers high-leverage spots only (7th inning+, 1–3 run game), so a single composite would mix scopes. The Relievers leaderboard shows a rolling 30-day window. Fired-manager teams get a sub-row showing the predecessor's own tenure separately.

Methodology

Counterfactual standings project each team's remaining games as if every lineup card had been the optimizer's recommendation. The math is a snapshot: winsFlip = round(seasonLineupCost / 10), added to the current win column and subtracted from the loss column.

Manager decision costs come from the same per-game decision audit used on /managers. Insights are emitted by templates under /methodology and refreshed hourly or nightly depending on the template tier.
