What does a +7.5% edge mean?

A positive edge of +7.5% means the price (+230) pays more than the fair price (+207). 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 30.3% 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 A+-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

AI breakdown

Verdict: This parlay offers a nice price lift over its original odds, making it an interesting SGP for today's tennis.

Value: the matchup there's no comparable market consensus to calculate a precise edge, your price of +230 is a good 10% higher than the original +200, which is always nice to see.
Market context: The significant 10% price lift you're getting compared to the original offer means you're seeing a favorable adjustment from the book.
Status: the matchup is no notable injury signal for Nakashima Brandon.
Social: the matchup isn't enough social data to provide a meaningful pulse on this specific bet.
Risk: This is a two-leg SGP, and multi-leg parlays inherently carry increased variance, especially when one leg involves an 'unmatched' market like Nakashima Brandon to win.

Smart insight: The outcome of the Nakashima Brandon to win leg will heavily influence the overall success of this bet, as a closely contested match (leading to more games) would also make his win more likely to be at a higher total. Similar profile: This is a classic tennis SGP combining a moneyline with a total games over, often seeing significant price shifts based on the expected competitiveness of the match. Counter-case: The biggest challenge here is that both legs rely on a competitive match where Nakashima Brandon ultimately prevails, so if he wins easily or loses quickly, this parlay is in trouble. Live context: the matchup lineups near tip-off.

Stake suggestion: the matchup it a fun-sized stake given the SGP nature and the thin market.

How this bet was graded

Grade A+ · 72/100 · Lottery Ticket

Boosted odds for Nakashima to win and Over 22.5 games at +230 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 (+10.0%), 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. A+ (72/100) 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 A+-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.
