What does a -2.3% edge mean?

A negative edge of -2.3% means the price (+150) is worse than fair value (+156). 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 40.0% 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 39.1%, which converts to fair odds of +156.

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 bet on Tuncay Duran winning the first set offers a solid price point for a single-leg play.

Value: the matchup there's no direct market consensus to compare against, your offered price of +150 provides good value relative to what one might expect for an otherwise unlisted outcome.
Market context: the matchup the absence of comparable market data or best alternative book prices, your offered price stands alone here.
Status: the matchup are no notable injury signals for this matchup.
Social: the matchup's insufficient public discussion to glean any social insights.
Risk: As a single-leg bet, the risk mainly comes from the inherent variance of a head-to-head tennis set.

Smart insight: This bet's value is highly dependent on Tuncay the matchup opening form and how quickly they can establish rhythm in the first set. Similar profile: the matchup moneyline bets in niche tennis markets often have thinner alternative markets, making direct value comparisons difficult but leaving more room for unique price offerings. Counter-case: The biggest challenge here is the lack of external validation for the fair odds, which means you're trusting the sportsbook's assessment of Tuncay the matchup probability. Live context: the matchup for any last-minute news or line movement before the match starts.

Stake suggestion: the matchup stake.

How this bet was graded

Grade B · 46/100 · Better Off Passing

Set 1 winner: Tuncay Duran at +150 on Bet365: 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 (46/100) 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.
