League base rates for the same games: home teams went 4–2 (n=6); market favorites went 3–3 (50.0%, n=6); overs went 1–4 against the line (n=6). Every model result above sits inside that backdrop.

The three largest totals misses account for 74.2% of the week's total absolute totals error (16.6 of 22.3 runs across 6 games).

Strongest call that landed

SD @ MIL (Oct 3): we had the home side at 60%; the home side won.

Final SD 2, MIL 3; opening price on that side -225; total 7; starter not verifiable for this game.
Strongest call that missed

ATL @ LAD (Oct 4): we had the home side at 65%; the away side won. It stays in the record.

Final ATL 3, LAD 2; opening price on that side -156; total 7; 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.

The biggest misses

We show them on purpose · totals, Sep 28 to Oct 4, 2026

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: Brier score

A rotating look at how we grade ourselves

For our moneyline probabilities, Brier squares the gap between the win probability we published and what happened (1 or 0), then averages it. 0.250 is a coin flip; lower is better. Reported live, never smoothed.
