Filter the board
Choose a league, market, side and minimum confidence. The strategy starts with the exact board you are researching.
Two records, kept separate
Save the filters behind a betting angle and Duban divides the record at that moment: historical results before the save date, forward results after it.
Example presentation only. Your strategy card uses the real graded Duban ledger and reports its own sample size and uncertainty.
One disciplined workflow
Choose a league, market, side and minimum confidence. The strategy starts with the exact board you are researching.
Duban freezes the filters and the save date. Historical results stay labelled as backtest evidence.
Every later qualifying pick is graded separately, so you can see whether the idea survives outside hindsight.
