Duckworth/Lewis Method of Re-calculating the Target Score in an Interrupted Match.

The Professional Edition of the Duckworth/Lewis shall be used in all matches. If any match is suspended after it has started such that the number of overs available to be faced by either side is reduced from that determined when the match started, the revised target shall be computed using the latest version of CODA as distributed by ICC in accordance with the instructions provided with that software and displayed on the screen. Where possible, arrangements shall be made for the provision of back-up capability, in case of computer malfunction, for the operation or continued operation of the Professional Edition. In the event of computer non-availability or malfunction where no such provision has been made, the Standard Edition (the method in use prior to October 2003) shall be used. The regulations given below describe only the operation of the Standard Edition, except that Clauses 4, 6 and 7 are also applicable to the Professional Edition.

These are not in direct proportion to the number of overs available to be faced, as with the average run rate method of correction. Instead they depend on how many overs are to go and how many wickets are down when the interruptions occur. To calculate the revised targets, you need to know the resources available at the stage of the match when suspensions and resumption of play occur. All possible values of resources have been pre-calculated and these are listed in the accompanying table. The table covers each individual ball in a game of up to 50-overs per side. The figures given in the table are percentages of the resources available for a complete 50-over innings. For matches with less than 50-overs per innings before they start,...
