Tabular model explanation

No game-specific tabular explanation was retained.

Eye-test prompt: which recorded input fits what you saw, and which would you question? A single win or loss cannot establish that the reasoning was right.

03 · Movement

What changed?

Recorded moneyline prices

Prices move at a fixed selection; a change in a totals line is a different contract. Collection runs independently of opening this notebook.

Latest available books and main / alternate totals

Current board coverage may no longer include completed games. An empty board is not proof that no historical quotes were collected.

Model snapshots

No retained movement series is available in the published summary. First/latest checkpoints remain above.

Recorded CLV compares the first and latest eligible pregame implied probabilities under the existing history policy. It is not a verified sportsbook closing tick. Missing or changed-selection comparisons stay unavailable.
