BookGrade + PulseScore
BookGrade measures what a price historically cost at a book. PulseScore measures how live each book's prices actually are. Neither is a betting signal.
A quality score, not a betting signal. It tells you what a price historically cost at a book, not which side to take.
These figures are transcribed from an internal study whose raw computation is not published. They are not an independent audit of the named sportsbooks.

Provenance
241 MLB clean-close games · 2026-05-22 to 2026-08-20 · MLB totals · pre-close only · mean(p_book - p_median_close), Shin no-vig reference, clustered by game.
What this measures
How far each book's pre-close prices historically sat from the cross-book consensus close, on MLB totals markets, averaged across 241 clean-close games.
What it does not measure
Which side to bet, whether a book is beatable, or whether a price is wrong. It is a quality score, not a betting signal.
Totals only. Spread-market BPQI is not shown here because spread numbers differ across books for non-vig reasons. A same-line filter is required before spread BPQI can be treated as price quality.
