What does a -2.3% edge mean?

A negative edge of -2.3% means the price (+200) is worse than fair value (+207). 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 33.3% 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 32.6%, which converts to fair odds of +207.

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

AI breakdown

Verdict: This SGP has the potential to be a fun bet, combining a star player's performance with a team outcome!

Value: With no comparable market consensus, assessing a quantitative edge versus fair odds isn't possible here. Your offer of +200 implies a roughly 33.3% chance of both events happening.
Market context: the matchup the nature of this SGP, there isn't a direct market to compare it to for consensus odds.
Status: the matchup is no notable injury signal for this bet.
Social: the matchup's not enough data from Reddit to gauge public sentiment on this specific bet.
Risk: 2-leg parlay variance. With 2 independent conditions required, hit rate compounds quickly and one miss voids the ticket. No verifiable correlation signal from the inputs provided.

Smart insight: the matchup scoring ability is a key driver for this parlay, and a high-scoring game for France would increase the chances of both legs hitting. Similar profile: This falls into the category of a player proposition linked with a team outcome in a soccer SGP. These can offer attractive prices due to their correlated nature. Counter-case: If Mbappe doesn't find the back of the net, this bet becomes much more difficult to hit, even if France advances. Live context: the matchup how the matchup offense is performing early in the match, and keep an eye on the matchup role.

Stake suggestion: the matchup stake.

How this bet was graded

Grade B · 41/100 · Better Off Passing

Mbappe to score and France to advance at +200 on Bet365 (2 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. B (41/100) 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 B-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.
