What does a -8.1% edge mean?

A negative edge of -8.1% means the price (+2000) is worse than fair value (+2186). 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 4.8% 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 4.4%, which converts to fair odds of +2186.

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.

AI breakdown

Verdict: This multi-leg parlay is an unfavorable offer despite the price adjustment.

Value: The price of +2000 is still significantly lower than the calculated an estimated fair price, resulting in a negative EV of -8.14%.
Market context: The offer comes in at +2000, 10.5% higher than its original price, but still trails the calculated fair odds by a substantial margin.
Status: No notable injury signal.
Social: the matchup public sentiment data to gauge.
Risk: This is a 3-leg parlay, inherently carrying high multi-leg parlay variance.

Smart insight: The outcome of the "Both Teams to Score" leg is likely to have the most significant impact on the overall value of this bet given the individual player prop variance. Similar profile: This type of bet profile (multi-leg SGP combining player props and team totals) often carries higher bookmaker margins due to perceived complexity.

Live context: the matchup lineups near tip-off.

Recommendation: Pass

How this bet was graded

Grade F · 39/100 · Better Off Passing

MAIN MEN ON TARGET: Colombia v DR Congo at +2000 on Bet365 (3 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 (+10.5%), 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 (39/100) 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.
