League base rates for the same games: home teams went 4–7 (n=11); market favorites went 6–5 (54.5%, n=11); overs went 4–6 against the line (n=11). Every model result above sits inside that backdrop.

The three largest totals misses account for 47.8% of the week's total absolute totals error (18.6 of 38.9 runs across 11 games).

Strongest call that landed

LAD @ ATL (Oct 7): we had the away side at 62%; the away side won.

Final LAD 4, ATL 1; opening price on that side -149; total 7.5; starter not verifiable for this game.
Strongest call that missed

CWS @ CLE (Oct 5): we had the home side at 55%; the away side won. It stays in the record.

Final CWS 4, CLE 3; opening price on that side -157; total 6.5; starter not verifiable for this game.

One week is a small sample. These are counts of where the results came from, not conclusions about skill; the season-long record is the number that matters.

What the market says

A market we deliberately don't model: the market's own record
MLB run line
42.8% of −1.5 favorites cover

Across 11,972 final regular-season games with a standard run line, the moneyline favorite laying −1.5 covered 42.8% of the time and won outright 58.3%. We publish no run-line projection, because the market prices this one efficiently, so this is the market's record, not ours.

Market benchmark, not a Nebula projection.

One number: Mean absolute error (MAE)

A rotating look at how we grade ourselves

Our totals number is graded on average miss: |projected runs − actual runs|. In our held-out research backtest the model's MAE is 3.52 runs versus the market's 3.46: we trail by 0.06. We say so plainly.
