Duckworth Lewis Method
3.2 For the resumption of play after the suspension, from the table note the resource
percentage now remaining for the revised number of overs/balls left and for the same
number of wickets lost.
3.3 Subtract the resource percentage in 3.2 from that in 3.1 to give the resource percentage
3.4 If a suspension in play causes the innings to be terminated, the resource percentage on
resumption (3.2) is zero and the percentage lost is the resource percentage which was
remaining when the suspension occurred (3.1).
3.5 If more than one suspension in play occurs, the resource percentages lost are calculated
as described in 3.1 to 3.4 and are accumulated to give updated values for the total
resource percentage lost or resource available for the innings. This is done after each
suspension as described in 5.2 and 5.5.
4. Penalties for Slow Over Rates
No overs penalties are imposed for slow over rates and hence slow over rates have no
effect on revised target calculations.
5. Calculation of Revised Targets
5.1 Note the number of overs per innings decided at the start of the game, N. From the table
note the resource percentage available to Team 1 at the start of their innings. (For N = 50
this is 100%.)
5.2 For all suspensions and any premature termination of Team 1’s innings, calculate the
total resource percentage lost using the procedure described in section 3. Subtract this
from the starting resource percentage (5.1) to give R1, the resource which was available
to Team 1 for their innings. Note Team 1’s total score, S.
5.3 There is no overs penalty for slow over rates by either side.
5.4 Note the number of overs allocated to Team 2 at the start of their innings and from the
table note the resource percentage for this number of overs remaining and 0 wicket lost.
This is R2, the resource percentage available to Team 2. If R2 differs from R1, which
will happen if Team 1’s innings was interrupted and/or Team 2’s was delayed, a revised
target must be set. Calculate this revised target, T, as described in 5.6 below.
5.5 For each suspension of play during Team 2’s innings or for premature termination of the
match, update the resource percentage available, R2, by subtracting the resource
percentage lost calculated as in section 3. Calculate the revised target, T, after each
suspension as described in 5.6 below. If the match has to be terminated, the result is
decided by comparing Team 2’s score at the time with the ‘par score’, this being the
value as calculated in the formulae for T in 5.6 below, but without the one run added. If
it is greater, Team 2 win. If it is equal, the match is tied. If it is less, Team 1 win.
5.6 If R2 is less than R1, Team 2’s revised target is obtained by reducing Team 1’s score S
in the ratio of R2 to R1, ignoring any figures after the decimal point, and adding one run
i.e. T = (S x R2/R1) + 1 (rounded down to a whole number, if necessary).
