Daily Doubles

The leg-two prices are final once the grid stops moving — which is not the moment leg one goes off. The pool keeps being counted for several minutes after the gates open, and most tote money arrives late: on Penn National R5 the double pool went from $938 at the scheduled off to $2,432 once it settled, moving one runner from 11.20 to 7.69. So a row only earns its final badge after two consecutive reads return an identical grid. Until then it is still moving and carries no badge. A settled row is the finished opinion of everyone who bet the double, on a race whose own win pool has not opened yet and which the bookmakers are still pricing. There is a filter for the settled ones. A double must be struck at one bookmaker, so parlays are priced per book across the books that quote both legs — never best-leg-one × best-leg-two, which invents a bet nobody can place. Leg pairings are verified against the racecard, because the source dashboard's own screen runs a race behind. Tote prices carry no overround (pool shares sum to 100%) but the real payout is lower by the track's takeout, which the dashboard does not publish — so a book beating these figures beats them by more in reality. Watch the pool size: a big number off a few hundred dollars is noise. The tote is not an unbiased yardstick, and measurements say so. Against Betfair SP over 1,029 races on 21 tracks across 9 days, the tote's favourite came out about 7% too long off the win pool and 10% too long off the final double, while its longshots were priced 13–45% too short — the classic favourite–longshot bias, stronger in the double pool, and exactly what a market with no layers to push a price in would produce. Betfair is near-perfectly calibrated over the same races (implied 39.6%, won 39.7%); the tote is not (implied 35.0%), so it is the tote that is wrong rather than two markets disagreeing. Cut by price rather than rank, the crossover sits around 5.0–8.0: under it the tote pays 7–9% more than the exchange, over it 11–45% less (at 20+ the tote showed 33.09 against Betfair's 47.92). The Signal column marks which side of that a row sits on. And the harder finding, from settled results. Every runner this page has shown is checked against Betfair's settled SP. In the first day's sample, selections where a book beat the tote by 5%+ were priced a median 34% below fair, and the book beat SP on only 3 of 34. The cause is not the tote — it is the bookmakers: these racing markets run roughly a 130% overround even taking the best of six books, so a typical price already sits 20–25% short of fair, and clearing the tote does not come close to clearing that. Beating the tote is therefore not evidence of value on its own. "Must beat the exchange" is on by default because it is the only screen that tests the thing that actually matters. Untick it to browse, not to bet. So the difference column is worth more on a short price than a long one, and the Exchange column is the check that matters: a book beating Betfair as well as the tote is the case that survives scrutiny.
