ICC 1995 Rain Rule for Limited Overs Internationals
Laws: Rain-rule for Limited Overs International Cricket
This was ratified at the July 1995 ICC meeting:
--[excerpt]--
10.3 Delayed or Interrupted Matches - Calculation of the Target Score
If the innings of the team batting second is delayed or interrupted and
it is not able to receive its full quota of overs, the target score shall
be calculated as follows: the score of the team batting first shall be
multiplied by the pecentage factor for the number of overs to be bowled
to the team batting second, as set out on the Target Score Calculation
Chart (Appendix A). Fractions shall be rounded to the next higher whole
number.
The percentage factors have been derived from a detailed from a detailed
mathematical analysis of a database of one day matches with the object of
establishing "normal" performance.
APPENDIX A
TARGET SCORE CALCULATION CHART
Overs % Factor
25 66.7
26 68.4
27 70.2
28 72.4
29 74.2
30 76.0
31 77.8
32 79.1
33 80.9
34 82.2
35 84.0
36 85.3
37 86.7
38 88.0
39 89.3
40 90.7
41 92.0
42 92.9
43 94.2
44 95.1
45 96.0
46 96.7
47 97.8
48 98.7
49 99.6
50 100.00
e.g. Team batting first score 188. The innings of the team batting second
is limited to 37 overs:
188 * 86.7% = 162.996
Target Score = 163 runs
--[end excerpt]--
Note: This gives absolutely no indication of how a match should
be treated when the first side does not face 50 overs, and the second
side faces even fewer overs. For example, in the 1995/96 India-Pakistan
match in Singapore:
India: 226 off 47.1 overs
Pakistan Target: 187 off 33 overs
Here is how I made it work:
Target = 226 * ( 33 over factor / 47.1 over factor )
= 226 * ( 80.9 / 97.9 ) where 97.9 is an estimation
of the 47.1 factor (47 ov = 97.8%)
= 186.75587
= 187
ODIs in Australia also do not use the above rain rule. The Australian
rain rule that is still in use is to take the highest scoring overs of
the team batting first, and then to deduct the target by 0.5% per over
lost.
