Simplified Approximation
This teaching demo uses a simplified formula for educational purposes. Official DLS uses proprietary resource tables maintained by the ICC. For official matches, use ICC-approved software.

| Scenario | Overs Available | Wickets Lost | Resource % |
|---|---|---|---|
| No interruption | Full (50) | 0 | 100% |
| Minor delay (10 overs lost) | 40 | 0 | 70-80% |
| Major stoppage (25 overs) | 25 | 0 | 40-50% |
| Loss + wicket (40 overs, 2 down) | 40 | 2 | 50-65% |
| Severe (20 overs, 5 down) | 20 | 5 | 20-35% |
Note: This is a simplified approximation. Official DLS uses complex ICC tables accounting for all overs/wicket combinations. Every wicket costs ~5-8% resources.
The Duckworth-Lewis-Stern (DLS) method is a mathematical formulation used to calculate target scores in limited-overs cricket matches interrupted by weather or other circumstances. It was devised by statisticians Frank Duckworth and Tony Lewis, and later refined by Professor Steven Stern.
The method works on the principle that teams have two resources to make runs: overs remaining and wickets in hand. When an interruption occurs, one or both teams lose resources. DLS calculates what percentage of resources each team had available and adjusts the target score accordingly, ensuring fairness regardless of when the interruption occurred.
Unlike simple run-rate calculations (which unfairly favor teams batting second in rain-affected matches), DLS recognizes that wickets in hand are just as important as overs remaining. A team with 10 overs and 9 wickets has far more scoring potential than one with 10 overs and 1 wicket remaining.
DLS uses resource percentages based on overs and wickets:
Official DLS uses complex tables showing resource percentages for every combination of overs remaining and wickets lost. For example:
Note: This teaching demo uses a simplified approximation. Actual DLS values come from proprietary ICC tables.
Team 1 scores 275 in 50 overs. Rain reduces Team 2's innings to 25 overs, and they've lost 3 wickets:
Run rate is unfair because it doesn't account for wickets in hand. If Team 2 needs 200 runs in 20 overs with 9 wickets left, they have far more scoring potential than if they had only 1 wicket left, but run rate treats both scenarios identically.
No. Official DLS uses proprietary resource tables derived from extensive cricket match data. This teaching demo uses a simplified mathematical approximation for educational purposes. Official matches must use ICC-approved DLS software.
The par score is what Team 2 would need to match Team 1's performance given their reduced resources. It represents a fair target based on the proportion of resources available. The revised target is par score + 1 (to win, not tie).
Yes, the official DLS method can handle multiple rain breaks and changing conditions. Each interruption recalculates available resources. This simplified teaching demo handles single-interruption scenarios for clarity.
Cricket strategy changes based on wickets in hand. With 9 wickets remaining, batsmen can take risks knowing support exists. With 1 wicket left, they must bat conservatively. DLS recognizes this by heavily weighting wickets in resource calculations.
DLS (Duckworth-Lewis-Stern) is the updated version adopted in 2014. Professor Steven Stern refined the original DL method to better reflect modern scoring patterns, particularly higher scoring rates in T20 cricket. The core principle remains the same.
Yes! If Team 2 has significantly reduced resources (fewer overs or wickets lost), their revised target will be proportionally lower. For example, if Team 1 scores 300 but Team 2 only has 50% resources, their target might be 151.
DLS is primarily used in ODI (One Day International) and T20 cricket where overs are limited. Test cricket doesn't use DLS because innings can be extended and there's no fixed over limit for result calculation.
