how results will come from Duckworth / Lewis Method?

Question

match stopped after 20 overs due to rain or light failure in one-day internationals

Answer 1

Results don't come from Duckworth ? Lewis method, but they say it is a formula which predicts the outcome, based on the conditions of the match that happened so far.

But with cricket being such an unpredictable game and depending on so many unpredictable factors like pitch, rain, dampness, wind etc. etc. - no method seem to be capable of predicting the result of any unfinished match. In any case I personally feel 20 overs is too short to apply any method to decide the fate of an unfinished match.

Answer 2

Duckworth and Lewis are 2 statisticians who wanted to make rain affected matches in cricket fairer. Previously if Team A made 200 in 50 overs and then it rained and Team B now had 20 overs there was a straightforward reduction of the target by 20/50 so that team B needed 81 to win. But they had an advantage as they still had 10 wickets to throw at the cause.

Thus Duckworth/Lewis looks at the resources that a team has left - those being overs AND wickets. A table is built up with overs left running down the left and wickets lost across the top with a percentage figure where the 2 meet.

Example

0 2 5 7 9

50 100.0 83.8 49.5 26.5 7.6
40 90.3 77.6 48.3 26.4 7.6
30 77.1 68.2 45.7 26.2 7.6
25 68.7 61.8 43.4 25.9 7.6
20 58.9 54.0 40.0 25.2 7.6
10 34.1 32.5 27.5 20.6 7.5
5 18.4 17.9 16.4 14.0 7.0

The real thing is much bigger as it must allow for every permutation.

So to take the simple example from earlier, Team B starts their innings with 20 overs and no wickets lost so the corresponding entry in the table is 58.9. This is a percentage and is multiplied against the original target to set a revised one - so 200 * .589 = 117.8, so the revised target is 117 which means they need 118 to win.

It is also used to decide who has won if a team chasing cannot complete their innings owing to rain etc.
So if Team A had made 200, and after 40 overs Team B were 150 - 5 and it began raining, who has won ?
Well Team B started with 100% of their resources - but at the moment of suspension had only 10 overs and 5 wickets left which the table reveals is 27.5% of their resources left.
So they have used 72.5% of their resources in the chase so far - so this figure is multiplied against the original target to set a new one.
200 * .725 = 145, so they had to have been at 146 or higher to have won the game - and they were !

Answer 3

This is a method in which is used if a match is stopped because of rain in cricket.

WHAT THEY DO
Like u made 200 runs in 50 overs
and now the other team is playing and there score is 100 in 20 overs and it suddenly rains that match cannot be played any more so they compare both the runs with the overs that the last team is playing like in 20 overs they are having 100 runs and u were having 99 then u lose by 1 run

Answer 4

Runs scored by the team batted first at the number of overs at which the match was stoped will be compared with the runs scored by the team batting second at the time of stoppage of the match and whoever has scored more runs at that point of time will be declared as winner.
