What is DLS method in cricket?
The Duckworth-Lewis-Stern (DLS) method is the official mathematical formula used by the ICC to set a revised target score for the team batting second when a limited-overs cricket match is interrupted by rain or bad light. Developed by statisticians Frank Duckworth and Tony Lewis and later refined by Steven Stern, it accounts for the two resources available to a batting side — overs remaining and wickets in hand — to fairly redistribute the run target.
How is DLS par score calculated?
DLS calculates the percentage of batting resources available to each team. Team 1's resource is 100% (full overs, no wickets lost). Team 2's resource is reduced proportionally by overs lost and wickets already fallen. The revised target is:
Revised Target = ⌈ Team1 Score × (Team2 Resources / Team1 Resources) ⌉ + 1
This calculator uses a standard simplified resource ratio. The official ICC DLS model uses proprietary exponential resource tables that account for non-linear scoring patterns.
