What does a -2.2% edge mean?

A negative edge of -2.2% means the price (+31207) is worse than fair value (+31911). 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 0.3% 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 0.3%, which converts to fair odds of +31911.

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 parlay combines some exciting sluggers for a truly massive potential payout!

Value: With no comparable market consensus available, the value here isn't quantified, but your offered price of +31207 certainly delivers a significant return if these longshots connect.
Market context: The absence of a comparable market makes it tricky to gauge against consensus, but a 4-leg home run parlay at this price is definitely in longshot territory.
Status: the matchup are no notable injury signals for any of the players in this parlay.
Social: the matchup isn't enough social media buzz to draw strong conclusions on this specific parlay.
Risk: This is a 4-leg parlay banking on individual home runs from four different hitters, which naturally carries high variance given the difficulty of hitting a long ball.

Smart insight: The value of this bet is most sensitive to the individual probabilities of each player hitting a home run. Similar profile: Longshot multi-leg HR parlays generally resolve below their implied probability due to the inherent difficulty and randomness of individual player performance. Counter-case: The biggest challenge here is the cumulative variance of needing four distinct, low-probability events to occur. Live context: the matchup lineups near tip-off to ensure all players are starting.

Stake suggestion: the matchup stake.

How this bet was graded

Grade F · 40/100 · Better Off Passing

4 leg parlay at +31207 on FanDuel (4 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 (40/100) 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.
