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.
