Duckworth Lewis Method HTML version
If R2 is equal to R1, no revision is needed and Team 2’s target is one more run than
Team 1’s score.
i.e. T = S + 1
If R2 is greater than R1, calculate the amount of excess resources, R2 – R1, and take this
percentage of the average 50-over total, G50, to give the extra runs needed, ignoring any
figures after the decimal point.
i.e. T = S + (R2 – R1) x G50/100 + 1 (rounded down to a whole number, if necessary)
6. Penalty Runs
6.1 During Team 1’s innings
If penalty runs are awarded to the batting side, then their score shall advance accordingly
and be taken into account when performing any future D/L calculation.
If penalty runs are awarded to the fielding side, then any D/L calculation in between
innings will be performed as normal, and their innings will commence with the score
equivalent to the number of penalty runs that they have been awarded.
6.2 During Team 2’s innings
If penalty runs are awarded to the batting side, then their score shall advance accordingly.
These penalty runs do not affect any subsequent D/L calculation.
If penalty runs are awarded to the fielding side, then there will be no recalculation of any
D/L target. Instead, the target score and the entire schedule of par scores will advance by
the appropriate number of penalty runs. If a loss of overs occurs after such a penalty has
been awarded, then the D/L target will be calculated based upon the original score of the
side batting first, and this target, and all par scores, will then be raised by the appropriate
number of penalty runs
7. The Result and its Description
When a revised target has been calculated and the match has been played out to its
completion, the result is described exactly as in the case of an uninterrupted match; if
Team 2 achieve their revised target they win by the number of wickets they have in hand
when they reach this score; if they fall short of their revised target by exactly one run the
result is a tie, and if they make a lower score Team 1 win by the margin of runs by which
Team 2 fall short of the score needed to achieve a tie.
When a match has to be abandoned with Team 2’s innings in progress (provided
sufficient overs have been bowled to constitute a viable match), the result is decided by
comparing Team 2’s score with the ‘par score’ as defined in 5.5 and the winning margin
is described in terms of the number of runs by which their score differs from the ‘par
score’, regardless of whether Team 1 or Team 2 are the victors.
Whenever a completed game has involved the use of the D/L method, the description
should be qualified by appending ‘(D/L method)’.
