Starting point: the league average, 22.75 points a team.
Scoring level: this season's mean miss so far, -0.83 a team, shrunk n/(n+64); adjusted starting point 21.92.
MIA pts / DET pts: the points each row adds to that team. Spread: the row's effect on the margin, green toward MIA, red toward DET (±1.2 scale). Total: its effect on the total, grey (±2 scale). Run. spread / Run. total: the line so far. Click a row for its stats.
v2.3: the shadow line's figures (MIA / DET points) where they differ by 0.05 or more; grey rows marked v2.3 are groups only it has.
In testing: each term added to v1.4 alone; its running columns are v1.4 with that term.

Shadow v2.3: v2.3 reads MIA 1.4 points stronger than v1.4 (DET 6.6 vs DET 8.0): Pace +0.9, Surface +0.6, Home field -0.4 (toward MIA); total 44.6 vs 45.5.

Paper rows at this run: totals check (paper, Monday): under 50.0

From the prediction ledger ([project record] Data/Prediction Ledger/). Each cell is a factor group's contribution to that team's projected points (coefficient x the value minus the training mean); the net-to-home bars share one scale, ±1.2 points (> beyond), green adds and red takes; the grey bar is the row's effect on the total (both teams' points together) on its own ±2-point scale. The running spread and running total start from the starting point (pick, twice the starting points) and end at the predicted spread and total. One line per page: the adopted line (v1.4); the shadow v2.3 appears only as small grey figures where it differs, and its own groups as grey rows. "In testing" lists any experimental term being tried. Each row is the group's marginal contribution from one joint fit of all the groups, so correlated groups (the quarterback and the team's offense; the team's own offense and the opponent's defense) share information without any point being counted twice. Nothing here is a bet.
