AHMEDABAD (Agencies) - The use of the much-debated Decision Review System in the World Cup has improved the incidence of correct decisions by five per cent, International Cricket Council chief executive Haroon Lorgat said on Wednesday. "To date, we have more than a five per cent improvement in correct decisions and I think we all want fundamentally for umpires to make the correct decisions. We don't want the game to hinge on something that is incorrect," Lorgat told reporters at a press conference. "After the tournament, we will review the success of the use of technology. In May, the ICC Cricket Committee will meet and a full report will be prepared by that committee. It will be brought back to CE's body and to the Board," he said. Lorgat backed the decision of the World Cup organisers to hold the summit clash of cricket's showpiece event at Mumbai's Wankhede Stadium which has a smaller capacity than some other grounds in India.
