INDEPENDENT DEVELOPER REFERENCE
Can I backtest a prop model with this data?
Not over seasons. Line recording began around 2026-11-03, statistics are limited samples, and no graded results are supplied. You can test a pipeline and collect your own forward sample, but any result covers a short window and is not a track record. Report its count and dates.
Editorial review: · Not a live coverage report
What you can do honestly
Archive rows daily from today, so that your own dataset records what was visible and when. Split by time, not at random. Independent ESPN statistics cover NBA, NFL and NHL as limited retained game samples, not full seasons. As of 2026-11-03 those samples were captured after the games were played, so they do not show what was known at game time. Read training data for the limits of each source.
