What does a -2.2% edge mean?

A negative edge of -2.2% means the price (+18556) is worse than fair value (+18976). 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 0.5% 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 0.5%, which converts to fair odds of +18976.

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 4-leg home run parlay is definitely a swing for the fences with an eye-popping offered price!

Value: the matchup there's no comparative market consensus, it's tough to quantify the value, but the offered price of +18556 on this four-leg longshot means a small wager could return significantly.
Market context: the matchup leg is a "To Hit A Home Run" prop, and those are generally priced for high variance.
Status: No notable injury signal for any of the players involved.
Social: the matchup currently insufficient data on Reddit to gauge public sentiment for this parlay.
Risk: This is a four-leg parlay consisting of individual home run props, which inherently carries high variance due to the low probability of each individual event.

Smart insight: The outcome of this bet will heavily depend on whether just one or two of these power hitters can connect, which would dramatically shift the odds in your favor. Similar profile: Longshot multi-leg parlays with "To Hit A Home Run" props are entertainment plays that offer substantial payouts for a small stake. Counter-case: The biggest challenge here is the natural difficulty of any four players hitting a home run in their respective games on the same day. Live context: the matchup lineups near tip-off to confirm all players are starting. Stake suggestion: the matchup.

How this bet was graded

Grade F · 38/100 · Better Off Passing

4 leg parlay at +18556 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 (38/100) 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.
