Duckworth-Lewis to review their formula for T20 matches

Duckworth said the duo would work on the method after collecting more data from the T20 World Cup. “We will be reviewing the application of the Duckworth-Lewis method to Twenty20 during the summer when this competition is over,” he was quoted as saying by ‘The Guradian’. “We thought it was appropriate to wait until the end of this competition when we’ve got a lot more Twenty20 data on our database.

“If there are any changes these should be ready for the commencement of the southern hemisphere season on October 1. My suspicion is there might be a slight difference but not very much,for instance that West Indian target of 80 might go to 81 or 82,” Duckworth added. Duckworth and Lewis,who are contracted by the International Cricket Council to update the system at periodic intervals,have rivals in an Indian company.

The Indian VJD method,used in the Indian Cricket League,would have set the West Indies a target of 94 from nine overs. But the English duo doubted the fairness of the Indian system. “He uses what we call a Delphic method. He tries to give people what they feel is a fair answer and he keeps fiddling his figures to do it. “The ICC commissioned a review of all the methods about four years ago and independent analysis showed that D/L was more rigorous and more capable of accommodating changes in the game than any other. So we’re confident we can hold up against all challengers,” they said.
