How the Doctor grades a slip

Records first

The Doctor checks published sports records for each leg: results, box scores, schedules, injury and lineup reports, venues and news. Your report shows the answers and their sources.

Read the source beside each answer and check where the evidence supports the pick or conflicts. The report’s plain-English take brings those findings together.

100 questions in 10 groups

Every leg is checked against the same bank of 100 sports-record questions, ten in each group. The depth changes how hard the Doctor looks, never the questions.

10. 10 Periods, Sequences & Live State

“X of Y applicable”

Questions that cannot apply are removed before anything is counted: 97 apply to football, 95 to tennis and 98 to basketball, hockey, baseball, soccer, MMA and boxing. Before a game, a lineup question with no published lineup counts as not applicable. The report then says how many of the applicable questions were answered, for example “79 of 97 applicable”.

• Answered

  A record answered it. The answer carries its source and how strongly it supports the pick.

• Unavailable

  The question applies, but no record could be checked in time. It is never filled in with a guess.

• Not applicable

  The question cannot apply to this sport or this slip, for example a lineup question before the lineup is published. It leaves the count.

The score and the evidence score

The answers and the prices become four factors and one score out of 100.

• Value

  Your saved price against the market consensus from other sportsbooks.

• Research

  The evidence score: how many applicable questions were answered and how strongly the answered records back the picks.

• Slip construction

  How the legs fit together: leg count, legs that depend on each other, and legs that cannot all win.

• Stake fit

  The stake against your own saved unit.

The letter

The score maps to a letter from A+ to F-.

Each Grade also shows where it ranks, for example “Scores higher than 59% of slips graded”.

What a Grade can’t know

Injuries break late. Lines move after the prices were read. Records describe the past, and the next game can go the other way. If the research cannot finish, the Grade says “Inconclusive” instead of guessing, and every unanswered question is shown as unavailable. A Grade is a read on price, evidence and build, not a win probability, and never a guarantee.

Questions people ask

How does BetSlip Doctor grade a bet slip?

The Doctor checks every leg against a bank of 100 sports-record questions in 10 groups, answering only from records it fetched. The answers and your price against the market become a score out of 100, and the score maps to a letter from A+ to F-.

What does “79 of 97 applicable” mean?

Questions that cannot apply to the sport or the slip are removed first (97 apply to football, 95 to tennis, 98 to most other sports). The first number is how many of the rest the Doctor answered from records.

What is the evidence score?

The evidence score shows how many applicable questions were answered and how strongly the answered records back the picks.

Is a Grade a win probability?

No. A Grade reads price, evidence and build. It never predicts a result and never guarantees one.

What changes with a deeper depth?

The 100 questions stay the same. Deeper depths expand the research behind the report.
