Formula

Revised Target = Team1 Score x (Team2 Resources / Team1 Resources) + 1

The Duckworth-Lewis method assigns resource percentages based on overs remaining and wickets lost. When an interruption occurs, the resources lost are calculated as the difference between resources before and after the break. The revised target is proportionally scaled by the ratio of resources available to each team.

Worked Examples

Example 1: Standard Rain Interruption

Problem:Team A scores 250 in 50 overs. Team B is 120/3 after 25 overs when rain stops play for an hour and 10 overs are lost. What is the revised target?

Solution:Team A resources: 100% (50 overs, 0 wickets lost).\nAt interruption: 25 overs remaining, 3 wickets down.\nResource before interruption (25 overs, 3 wkts) = approx 42.5%.\nResource after interruption (15 overs, 3 wkts) = approx 29.8%.\nResources lost = 42.5% - 29.8% = 12.7%.\nTeam B total resources = 100% - 12.7% = 87.3%.\nRevised target = 250 x 0.873 + 1 = 219.

Result:Team B needs 219 to win from 40 overs (99 more runs from 15 overs, RRR: 6.60)

Example 2: First Innings Shortened by Rain

Problem:Rain stops Team A's innings at 35 overs with a score of 200/6. Team B gets a full 35 overs to bat. What is the target?

Solution:Team A resources used: resource(50,0) - resource(15,6) = 100% - 18.5% = 81.5%.\nTeam B resources: resource(35,0) = approx 83.4%.\nSince Team B has MORE resources (83.4% > 81.5%), runs are added.\nExtra resources = 83.4% - 81.5% = 1.9%.\nExtra runs = G50 x 1.9% = 245 x 0.019 = 5 runs.\nRevised target = 200 + 5 + 1 = 206.

Result:Team B needs 206 to win from 35 overs (RRR: 5.89)
