The question behind the result
For First Five Innings Run Line, the selected side's rating edge comes from Team rating versus Opponent rating, with Venue adjustment applied afterward. The probability row evaluates Market spread against that margin using Margin standard deviation.
Field-by-field source review
Market spread records selected team spread. Negative means favored. For projected margin, Margin standard deviation represents estimated game-to-game variation.
As a practical check, a source revision should stay visible rather than being blended into an unrelated adjustment.
What can move the baseline
For this comparison, starting pitcher, bullpen workload, park, weather, batting order, and handedness should be current for the scheduled game.
On this page, a pitcher or lineup change can invalidate a projection before the posted price visibly moves.
