You wont get a better answer than this.

lol at asterix in that question.

The Duckworth Lewis method or D/L method is a set of formulas and tables created by Frank Duckworth and Tony Lewis. The method was adopted by the International Cricket Council (ICC) in 1999 to address the problem of delayed one-day cricket matches for reasons of rain, poor light and floodlight failures although it has also been used in events that have been shortened due to crowd problem, sandstorms and even snowstorms.

V give good answer

In the sport of cricket, the 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 Twenty-20 cricket match interrupted by weather or other circumstance. It is generally accepted to be a fair & accurate method of setting a target score, but as it attempts to predict what would have happened had the game come to its natural conclusion, it generates some controversy. The D/L method was devised by two English statisticians, Frank Duckworth & Tony Lewis.

D/l is the method no body can undestand
only four men is understand
one is umpire
second one both caption
and third one is match raffrii
it is curse for the second bating team
lol
sorry actually l cant know
so l joking that

it is an misunderstaneble & miscalculated method method for loosing team gifted method winning team and unjustified method for both the team. (rather using this method just declare match is drawn)

The Duckworth-Lewis Method (1999)
An introduction to the D/L (Duckworth/Lewis) method of resetting targets in interrupted one-day cricket matches by Frank Duckworth & Tony Lewis


The D/L method of resetting targets in rain-affected one-day cricket matches has now been in use for well over two years & has been adopted for use in most test playing countries of the world. And it is the 'rain-rule' in use for the 1999 World Cup competition played in May & June & hosted by the England & Wales Cricket Board.

The method is the invention of Frank Duckworth & Tony Lewis. Frank is a consultant statistician & editor of the Royal Statistical Society is monthly news magazine, RSS NEWS. Tony is a lecturer in mathematical subjects in the Faculty of Computer Studies & Mathematics at the University of the West of England, Bristol & chairman of the Western Branch of the Operational Research Society

The method that they have invented is simple to apply provided one is prepared to take a few minutes to understand its logic. The calculations can easily be performed using nothing more than a single table of numbers & a pocket calculator although a purpose built computer program is available to undertake the calculations accurately & quickly in match situations (see further information on this below). With a little practice, however, there is no reason why anyone should not be able to calculate the revised target & in quick time. The authors firmly believe that the method is simple enough for it to be adopted for use at all levels of limited-overs cricket. This article provides a summary of the way the method works.

Basis of the method

The D/L method works using the notion that teams have two resources with which to make as many runs as they can - these r the number of overs they have still to receive & the number of wickets they have in hand. From any stage in their innings, their further run-scoring capability depends on both these two resources in combination. The table gives the percentage of these combined resources that remain for any number of overs left & wickets lost. An extract from the table is given in Table 1. Information is provided later on how the full table can be obtained, including the ball-by-ball version which is used when stoppages occur mid-over.

When a match is shortened after it has begun, the resources of one or both teams r depleted & the two teams usually have different amounts of resource for their innings. In this case a revised target must be set. The D/L method does this in accordance with the relative resources available to the two teams. If stoppages cause the team batting second (referred to here as Team 2) to have less resources available, as is more often than not the case, then their target will be revised downwards. If, on the other hand, as often happens when Team 1 is innings has been interrupted, the stoppages usually result in Team 2 having more resources available & then their target is revised upwards to correct for the extra resources they have at their disposal.

Reading the table

The single table applies to all lengths of one-day matches from 50 overs-per-side downwards. Because this length of match is by far the most common, the resources listed in the table r expressed as percentages of those available at the start of a 50-over innings. Thus when there r 50 overs still to be received & no wickets have been lost, the resource percentage available is 100%. A 40-over innings starts with a resource percentage of 90.3% relative to a 50 over innings. An innings shortened to 25-overs before it starts commences with a resource percentage of 68.7% relative to 50-over innings. (Although such innings have only half the overs of a 50-over innings they have all 10 wickets & so have much more than half the resources.)

In order to determine the correct resource percentage the batting side has remaining at any stage of its innings, the number of overs left must be identified. This number of overs left, in conjunction with the number of wickets lost, is then used to read the resource percentage remaining from the table.

For example, suppose that after 20 out of 50 overs a team have lost 2 wickets. They have 30 overs left. From the table u will see that the resource percentage remaining is 68.2%.

Suppose now that there is an interruption in play & 10 overs r lost from the innings. When play can resume there r only 20 overs left but there r still, of course, 2 wickets down, & the table now tells us that the resource percentage remaining is 54.0%. Thus the shortening of the innings has caused the team to lose a resource pe
