Darts research that looks past the three-dart average.

BAI8 researches the match and sets each player’s chance next to the bookmaker’s price. Checkouts, throw order and the deciding leg are read, not assumed.

Darts

Darts is won on the double, not the average.

The average says how a player scores. A leg is won by finishing it.

  1. Average and checkout percentage

    Scoring and finishing read side by side, because the leg is won on the double.

  2. Throw order and the deciding leg

    Legs split by who threw first, and who holds up in a last leg.

  3. Form and pressure on the double

    Finishing under pressure, with a stage effect treated as noisy, not permanent.

  4. How long the format is

    A best of 11 lets an upset through where a best of 19 tends not to.

  5. Travel and the schedule

    Three events in nine days arrive on the oche with the player.

  6. Every market read on its own

    A handicap gets its own chance, never one guessed from the match price.

Nothing hidden. Every number shows its working.

See what was read, which findings moved the chance and by how much.

How every number is made

  1. Research the match

    Thirteen passes, one question each: injuries, form, tactics, schedule, conditions, officials.

  2. Weigh every source

    A finding counts only as much as its sources earn. A stale or late source scores zero.

  3. Cap every finding

    No finding can move the number far, and a weakly sourced one moves it less.

  4. Price every outcome

    The findings become one chance per result, adding up to exactly 100%.

  5. Then check the price

    Only now does the price come in. Where our chance beats it, you see the gap.

What stands behind it

Built by engineers and AI agents. Every figure here is read from the code.

54 instruments draw each sport the way its fans read it. Prices are checked against 72 bookmakers. More than 7,000 automated tests run before every release.

Four rules every run follows

Whole, or refunded

A failed pass is retried deeper. A run that still cannot finish is never published, and your credit comes back.

The price stays out of it

No research pass sees the bookmaker’s odds, so our chance cannot copy theirs.

Refreshed before the start

Re-run four times before the start, at no cost to you.

At 72 hours, 24 hours, 6 hours and 75 minutes before the start.
Nothing hidden

Every finding shows what it did to the number and links to what it read.

Four places to ask. One shows the working.

One question, put to each: Luke Littler v Luke Humphries. Example data.

How much work goes into the answer?

13 research agents read the match, often for over an hour.

10 findings from 432 pages read, 27 cited
  • Agent 1 Availabilityno change
    Both are through to the evening session

    Both won their afternoon matches, the order of play lists this one, and the PDC has published nothing about either player. The pass looked and found nothing, which is a result rather than an absence of one.

    80% confidence
  • Agent 2 Form & underlying play+1.1%from 3 findings
    Littler’s scoring sets the pace on tour

    His three-dart average over recent events sits at or near the top of the tour and above Humphries’. The gap holds against top-sixteen opponents, not only in early rounds.

    80% confidence
  • Agent 3 Tactics & style+1.3%from 2 findings
    Littler reaches a finish earlier in the leg

    He sets up more legs in fifteen darts or fewer than any other player, so Humphries often has one visit fewer to finish. Against the throw this is how breaks happen.

    76% confidence
  • Agent 4 Matchup history+0.3%from 1 finding
    Littler has won more of their recent short-format meetings

    Their recent meetings over short formats have tilted Littler’s way, mostly through breaks of throw. Longer formats and older meetings are discounted heavily.

    64% confidence
  • Agent 5 Historical comparables+0.8%from 2 findings
    Average gaps convert slightly better than the start says

    In a ten-season sample of best-of-11 PDC stage matches, the player with the higher recent average won a little more often than the starting figure implied. The pattern held in both halves of the sample.

    70% confidence
  • Agent 6 Rest, load & travelno change
    A similar day’s load before this match

    Both won their afternoon matches in a similar number of legs and have the same break before the evening session. Travel to Basel was the same for both, and travel alone is not fatigue.

    70% confidence
  • Agent 7 Weather & venueno change
    Nothing in the venue moves this

    An indoor arena with a standard European Tour stage, a neutral crowd for two English players, and both are seasoned stage players. The pass looked and found nothing, which is a result rather than an absence of one.

    70% confidence
  • Agent 8 Stakes & incentivesno change
    The same title and ranking money for both

    Prize money here counts to the same rankings for both players. Needing a result is not the same as being able to get one, and the pass found nothing that separates them.

    66% confidence
  • Agent 9 Officiating & disciplineno change
    The referee has nothing to say about this one

    Scores are called and checked, and the rules apply the same to both players. There is no mechanism here worth applying.

    72% confidence
  • Agent 10 Public information environmentno change
    Nothing new came out of the afternoon interviews

    Both players spoke after their afternoon matches. No change of equipment, schedule or plan was mentioned, so there is no information event to apply.

    74% confidence
  • Agent 11 Reporting consensusno change
    Confirmed by two independent sources

    A second stats service and a specialist outlet reached the same conclusion from their own figures. Independent confirmation raises how far the claim is trusted.

    82% confidence
  • Agent 12 Universal-pattern hypothesesno change
    A walk-on claim, written up and given no weight

    A widely shared claim that the player who walks on second wins more often was written as a precise rule for the registry to test. Until it survives a holdout, it moves nothing.

    50% confidence
  • Agent 13 Adversarial review−0.6%from 2 findings
    Eleven legs is short enough for one bad spell

    A best of 11 lets a run of missed doubles decide the match, and Humphries is the steadier finisher. Part of the scoring edge is taken back.

No. It holds no bookmaker account and never moves your money. Recording a bet as real only adds it to your own ledger.

A bet you record at the price you were shown, with a stake you choose and no money involved. It is graded by the result like any other. Watching records the call with no stake at all.

You upload a screenshot of a bet. BAI8 reads each leg and prices the whole bet, including legs that depend on each other. A leg it cannot read is marked unread, never guessed.

From the research, never from the bookmaker. An assessment builds each chance from the match’s own evidence, and every finding is capped and weighted by how credible its sources are. Only then is the price brought in to compare. Before an assessment, there is no number.

As long as the match needs, often more than an hour. Thirteen research passes read the match, and every source they find is graded for credibility and weighted by it. If a run cannot finish, the credit is refunded.

One assessment of one match. Opening one somebody else has already run costs a credit too, and re-reading one you hold is free. A new account gets five credits to try BAI8, valid for ten days. Every plan includes credits, and packs bought on their own never expire.

BAI8 compares prices at more than seventy bookmakers, each matched to the countries that license it, and shows them in your odds format, your currency and one of six languages. Use BAI8 only where betting is legal for you.

Your edge is the gap between our chance of a result and the chance the price implies. A positive edge is an estimate, not a promise. 18+, bet lawfully where you are. Betting loses money for most people who do it.
