What does a -16.8% edge mean?

A negative edge of -16.8% means the price (+450) is worse than fair value (+561). You can still win, but the long-run math is against you.

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

No. The market still implies about a 18.2% 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 the available market price, we estimate 15.1%, which converts to fair odds of +561.

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 F-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

Without a confirmed fair price, the responsible call is patience. Re-check closer to game time when more books post.

AI breakdown

Verdict: This boost offers negative expected value and is not recommended.

Market context: The sportsbook's boosted price of +450 is considerably lower than the devigged an estimated fair price, showing poor value.
Status: No notable injury signal.
Social: the matchup is insufficient data to assess social sentiment.
Risk: 5-leg parlay variance. With 5 independent conditions required, hit rate compounds quickly and one miss voids the ticket. No verifiable correlation signal from the inputs provided.

Smart insight: The value of this bet is highly sensitive to the true probabilities of each leg, and deviations from the fair odds in any leg will significantly impact the overall EV. Similar profile: This is a 5-leg same-game parlay focusing on individual player prop counts (fouls committed, shots, fouls won) in soccer, a category that often resolves below aggregated fair odds due to correlation not accounted for in boost pricing. Counter-case: The primary reason to fade is the strong negative expected value calculated against the fair odds. Live context: the matchup lineups near tip-off.

Recommendation: Pass

How this bet was graded

Grade F · 26/100 · Better Off Passing

Bet Builder: Scotland vs. Morocco at +450 on DraftKings (5 legs): we couldn't match this slip to enough comparable market prices to compute a trustworthy consensus fair value, so no edge % is shown — anything we'd print would just echo the book's own vig. The grade leans on price lift vs the original (+0.0%), leg count, and variance. Treat it as directional.

Frequently asked questions

Why isn't an edge % shown?

We couldn't match this slip to enough comparable market prices to compute a trustworthy fair value. Rather than show a number derived from the offered price itself (which would just echo the book's vig), we leave the edge unstated. The grade still reflects price lift vs the original, variance, and confidence.

Does the grade still mean something?

Yes. F (26/100) is built from the price lift, leg count, variance, and any verified context signals — it's directional. Treat it as a sanity check, not a precise EV figure.

Should I bet every A-grade ticket?

Grading is a price-quality signal, not a prediction. Even an F-grade ticket can lose. Size within your bankroll, account for correlation between legs, and use Inside Angles above to spot factors the price hasn't absorbed yet.
