Duckworth-Lewis Formula:
| From: | To: |
The Duckworth-Lewis method is a mathematical formulation designed to calculate the target score for the team batting second in a limited-overs cricket match interrupted by weather or other circumstances. It's the standard method used in international cricket, including T20 World Cup matches.
The calculator uses the Duckworth-Lewis formula:
Where:
Explanation: The method accounts for both overs remaining and wickets in hand to determine the resources available to a team.
Details: In T20 World Cup matches where weather often interrupts play, the Duckworth-Lewis method provides a fair way to adjust targets and determine results in rain-affected matches.
Tips: Enter the par score (usually the first team's score in a chase) and the percentage of resources lost (as determined by official DLS tables). The calculator will compute the revised target.
Q1: Why use Duckworth-Lewis in T20 cricket?
A: It's the most scientifically developed method to fairly adjust targets considering both overs and wickets remaining when play is interrupted.
Q2: How is resources lost calculated?
A: Official DLS tables combine overs remaining and wickets in hand to determine the percentage of resources lost.
Q3: When is Duckworth-Lewis applied in T20 matches?
A: When weather or other factors prevent completion of both innings, and at least 5 overs have been bowled to the team batting second.
Q4: Are there limitations to this method?
A: It can be complex to understand, and some argue it doesn't always account for match context like momentum or pitch conditions.
Q5: Is this the same as VJD method?
A: No, VJD is an alternative method used in some domestic competitions, while DLS is standard in international cricket including T20 World Cup.
