Rain-affected Targets
There will be no change to the way that the well-established D/L method works, which is described in published books and summarised on the Cricinfo webpage. Lewis said that the effects of the new tables "will in most cases be to lower slightly the enhanced targets when the first innings is interrupted and to raise slightly the D/L par scores during the early part of the reply". Duckworth and Lewis felt
that it was in the interests of the game that the D/L method should be
stable whilst the world got used to it. "The time is now ripe to reflect
recent advances in the game" they said
Here is an extract of the
new tables
Effects of the new tables
Example 1: Premature curtailment
of Team 2's innings
Team 1's innings: this was
uninterrupted, so the resource percentage available is 100%
Team 2's innings: resource % available at start of innings = 100% After 40 overs Team 2 have
10 overs left and have lost 5 wickets.
As play is abandoned all
this remaining resource is lost.
Team 2 had less resource
available than Team 1 and so to give the target Team 1's score must be
scaled down by the ratio of resources, 73.9/100.
As there is to be no further
play, the winner is decided according to whether or not the par score has
been exceeded. With 199 runs on the board, they have exceeded this by 15
and so are declared the winners by 15 runs.
-------------------------------------------------------------------------------- Example 2: Interruption to
Team 2's innings
Team 1's innings: At the
start of 40 over innings resource percentage available =
89.3%
Team 2 had less resource
available than Team 1 and so to give the target Team 1's score must be
scaled down by the ratio of resources, 78.6/89.3 Team 1 scored 200, so
Team 2's 'target' is 200 x 78.6/89.3 =176.04 which rounds down to 176 to
tie with a revised target of 177. They then require a further 37 runs to
win from 5 overs with 5 wickets in hand.
-------------------------------------------------------------------------------- Example 3: Interruption to
Team 1's innings
Because of the different stages of the teams' innings that their 10 overs are lost, they represent different losses of resource. Team 1 have lost 7 wickets and had 10 overs left when the rain arrived and so from the table you will see that the premature termination of their innings has deprived them of the 17.9% resource percentage they had remaining. Having started with 100% they have used 100 - 17.9 = 82.1%; in other words they have had 82.1% resources available for their innings. Team 2 will also receive 40 overs. With 40 overs left and no wicket lost you will see from the table that the resource percentage which they have available (relative to a full 50 over innings) is 89.3%. Team 2 thus have 89.3 - 82.1 = 7.2% greater resource than had Team 1 and so they are set a target which is enhanced by 7.2% of 235, or 16.92, more runs than Team 1 scored. [235 is the revised average in 50 overs for ODIs in recent years] Using the sum 190 + 16.92 = 206.92, rounding down gives 206 to tie and Team 2's target is 207 in 40 overs. Note: Most other target resetting
methods previously used would make no allowance for this interruption.
They set the target of 191 simply because both teams are to receive the
same number of overs. This is clearly an injustice to Team 1 who were pacing
their innings to last 50 overs when it was curtailed, whereas Team 2 knew
in advance of the reduction of their innings to 40 overs and have been
handed an unfair advantage. D/L neutralises this by setting Team 2 an enhanced
target over the number of runs Team 1 actually scored.
