Does a positive edge mean the bet is likely to win?

No. The market still implies about a 42.0% chance this hits at the offered odds. A +EV bet pays more than its true probability warrants — most +EV bets at long odds still lose individually.

How are fair odds calculated?

Sportsbook prices on the same market are de-vigged and averaged to estimate a true win probability. Using a consensus of 11 sportsbooks, we estimate 41.8%, which converts to fair odds of +139.

Why does this grade differ from the sportsbook's advertised lift?

Books quote lifts vs their own original line, which already includes margin. We compare the price to a vig-free consensus, so an advertised lift can still grade poorly if the underlying line was inflated.

Should I bet every bet that grades well?

Grading is a price-quality signal, not a guarantee. Even a A-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

Chicago White Sox — A Grade — Good Value Play (51/100)

Q: What does a -0.4% edge mean?

A negative edge of -0.4% means the price (+138) is worse than fair value (+139). You can still win, but the long-run math is against you.
