Frequently Asked Questions

What is the DLS (Duckworth-Lewis-Stern) method in cricket?

The DLS method is a mathematical formula adopted by the International Cricket Council (ICC) to calculate revised target scores and determine winners in rain-interrupted limited-overs cricket matches based on the percentage of batting resources (overs and wickets) remaining.

How is the revised target calculated when overs are reduced?

If Team 2 has fewer resources available (R2 < R1), the revised target is Target = Floor(Team 1 Runs * R2 / R1) + 1. If Team 2 has more resources, an adjustment based on the standard average score (G50) is added.

What is the minimum number of overs needed for a valid DLS result?

According to ICC rules, a minimum of 5 overs per side must be completed in T20 matches, and a minimum of 20 overs per side must be completed in ODI matches for a valid official result.

What is the difference between Target Score and Par Score?

The Par Score is the exact score needed by Team 2 to be level or tied with Team 1 at any given over and wicket loss. The Target Score is the total runs required to win (Par Score + 1 run).
