Overs remaining are rounded to the nearest whole over for the table lookup, exactly as the over-by-over Standard Edition sheet works.
How the DLS par score works
In cricket, a team has two resources for scoring runs: overs and wickets. When rain takes overs away, the Duckworth-Lewis-Stern method measures how much scoring resource was lost, using a published table of resource percentages. The par score then scales Team 1 total down in the ratio of the resources each team had:
- Read the resource percentage with the overs remaining and wickets lost before the rain.
- Read the resource percentage with the overs remaining and wickets lost after the rain.
- The difference is the resource percentage lost.
- Subtract it from Team 2 starting resources to get R2.
- Par = Team 1 score x R2 / R1, rounded down to a whole number.
About the resource table
This calculator embeds the full Duckworth-Lewis Standard Edition table: resource percentages remaining for overs 0 to 50 and wickets lost 0 to 9. A full 50-over innings with no wickets lost equals 100% of resources. Notice how losing wickets hurts far more late in an innings: with 10 overs left and no wickets lost a team still has 32.1%, but with 5 wickets lost only 26.1%.
