What does a +46.4% edge mean?

A positive edge of +46.4% means the price (+24547) pays more than the fair price (+16734). Over many identical bets, that gap is your expected return per dollar staked.

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

No. The market still implies about a 0.4% 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 0.6%, which converts to fair odds of +16734.

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 quadruple home run parlay offers significant theoretical value due to the boosted odds.

Market context: The boost increases the payout by 49.7% from the original odds, offering a large premium over the calculated fair price.
Status: the matchup is no notable injury signal for any of the players involved.
Social: the matchup social media data was retrieved for this boost.
Risk: This is a 4-leg parlay, inherently carrying high multi-leg parlay variance amplified by the longshot nature of each "To Hit A Home Run" prop.

Smart insight: The value of this bet is highly sensitive to the true individual probabilities of Yordan Alvarez, Kyle Schwarber, Willson Contreras, and Pete Alonso hitting a home run. Similar profile: This is a multi-leg "To Hit A Home Run" parlay, a category often presenting longshot payouts but with rare hit rates against fair value. Counter-case: The primary risk is the extremely low individual probability of each player hitting a home run, compounded across four legs. Live context: the matchup lineups near tip-off.

Recommendation: Small

How this bet was graded

Grade B · 74/100 · Lottery Ticket

4 leg parlay at +24547 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 (+49.7%), leg count, and variance. Treat it as directional. Situational nudges applied: Public/Sharp split (-1).

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 (74/100) 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.
