Duckworth–Lewis method (D/L method)

According to Wikipedia Definition : Duckworth–Lewis method (D/L method) is a  mathematical way to calculate the target score for the team batting second in a one-day cricket or Twenty20 cricket match interrupted by weather or other circumstance.


How To Calculate The D/L Method

The D/L method was created by two British statisticians, Frank Duckworth and Tony Lewis.

It was first used in international cricket in the second game of the 1996/7 Zimbabwe versus England One Day International series, which Zimbabwe won by 7 runs and was formally adopted by the International Cricket Council in 2001 as the standard method of calculating target scores in rain shortened one-day matches.

The essence of the D/L method is 'resources'. Each team is taken to have two 'resources' to use to make as many runs as possible: the number of overs they have to receive; and the number of wickets they have in hand.

At any point in any innings, a team's ability to score more runs depends on the combination of these two resources.

Looking at historical scores, there is a very close correspondence between the availability of these resources and a team's final score, a correspondence which D/L exploits.
