The Most Productive Overs (MPO) method was a mathematical formulation designed to calculate the target score for the team batting second in a limited overs cricket match interrupted by weather or other circumstances.
[1] MPO was used most notably during the 1992 Cricket World Cup, and the controversial effect of its application during the England v South Africa semi-final directly led to the development of the current, Duckworth–Lewis–Stern, method.
Under the average run-rate method, the revised target was 108, meaning the West Indies needed 61 off the 11.2 overs that remained (a required RR of 5.38).
After the West Indies won the match (and the competition) by eight wickets with 4.4 overs remaining, Australian fans loudly booed this unsatisfactory conclusion, which was criticised by the media and Australia's captain Allan Border.
While these modifications reduced Team 1's advantage, they only addressed the fourth intrinsic flaw of the method.
