The public record
Every projection we posted, graded
These numbers were published before the games were played and scored against the box score afterward. Nothing is added after the fact, nothing is removed once graded, and the misses are here with the hits. This is the live forward record — the after-the-fact validation lives on the retrospective backtest, and the two are never combined.
Grading began 2026-08-03 · data source: live repo · free and un-gated, permanently.
Record accruing — 2 nights graded. A sample this small says very little about long-run accuracy; the honest read arrives after a few weeks. The page updates itself every morning whether the numbers flatter us or not.
Calibration — stated probability vs what happened
When the model says 62%, does it happen 62% of the time? Bands with no projections yet are shown empty rather than hidden.
The same measurement on 4,570 held-out 2025 starts is on the backtest page. That one is retrospective; this one is not.

- · Projections are issued before first pitch and timestamped with the model version that produced them.
- · A projection may be re-issued if the probable starter changes. The re-issue supersedes the original, both are kept, and only the live one is graded — grade-once, never twice.
- · Once a row is graded it is immutable. No row is edited, hidden, or deleted, whatever it says.
- · The line used for grading is the consensus line across captured books, chosen before the game.
- · If a pitcher is scratched, the row voids and is reported as a void rather than scored.
- · Model versions are published. A model that fails its validation gate is not shipped — the outs and earned-run models failed twice and never went live.
What this record is not
It is a record of projection accuracy, not of profit. We take no positions and track no returns, so there is no ROI or closing-line-value figure here and there will not be one until positions are actually tracked. These are projections, not picks — what you do with them is your call.
