DLS Target Calculator

What is the DLS Method?

The Duckworth-Lewis-Stern (DLS) method is a mathematical formulation used to calculate revised targets in limited-overs cricket matches interrupted by weather or other circumstances. It takes into account the number of overs remaining and wickets in hand to set a fair target.

Formula Components

When to Use

• Rain-interrupted matches
• Matches with other delays
• Reduced overs scenarios
• Tournament planning

Key Concepts

• Resources:
  • Based on overs remaining
  • Affected by wickets in hand
  • Percentage calculated from standard tables
• Par Score:
  • Minimum target to win
  • Adjusted for lost resources
  • Updates with each interruption

Historical Context

The DLS method was developed by Frank Duckworth and Tony Lewis in the 1990s, and later refined by Steven Stern in 2014. It replaced the previous methods which were considered less fair:

• Average Run Rate method (pre-1992)
• Most Productive Overs method (1992-1995)
• Original DL method (1997-2014)
• Current DLS method (2014-present)

Advantages

• Accounts for match situation
• Considers modern scoring patterns
• Fairer than previous methods
• Widely accepted internationally
• Regular updates to stay current
