In the controversial 2009 West Indies vs England ODI, West Indies coach John Dyson made a D/L method miscalculation when he asked his batsmen to come off for bad light. The key factor he ignored was that a wicket had fallen on the last ball, which significantly changed the D/L calculation. He calculated based on the score at 33 overs, not accounting for the wicket loss. Required run rate and balls left are standard D/L factors, but the wicket loss was the critical missed factor.
