About
Our numbers, not the books'
Sportsbooks set lines to balance action and protect a margin. We set ours to be right.
- 1Project it ourselves
We model every game from scratch — before we look at a single sportsbook line.
- 2Convert to a fair line
A 60% win probability is a fair -150. A 40% shot is +150. That's our number.
- 3Compare to the book
Only when the book's price is meaningfully off our fair line do we call a play.
p ≥ 50%: line = −100·p / (1−p)
p < 50%: line = +100·(1−p) / p
p < 50%: line = +100·(1−p) / p
Verdicts
We LikeBig gap between our number and theirs. Our strongest call.
LeanReal edge, smaller margin.
ContrarianWe like the side the public hates — and the price pays for it.
TrapLooks easy. The price says otherwise. Stay away.
NO PLAYBook's line is basically ours. No edge, no bet.
