THE PINNACLE LINE

Phase 1: Foundations

The vig and the break-even number

Most bets are priced at -110. You risk 1.10 to win 1.00. That built-in cut is the vig, and it is how a sportsbook gets paid.

Because of it, winning half your bets is not enough. At -110 you need to win about 52.4% to break even (110 divided by 210).

Example only, 100 flat bets of 1u at -110:

Many bettors see 55% as a strong long-run rate at -110. Even then, 45 of every 100 bets lose. If each bet is independent, a run of 5 or more straight losses shows up in about 65% of 100-bet stretches. A cold streak does not prove a broken process.

Where it shows up in our plays: the price limit and CLV exist because a few cents of price move the break-even number, and we want the best price available.

What cuts against it: these are averages. Any one stretch can look better or worse, and 100 bets is still a small sample.

Takeaway: win rate alone means nothing until you know the price.
