Net Run Rate (NRR) is used in GMCL to differentiate equal points positions in League Tables.
So what is NRR?
The basic principle is
Runs scored divided by overs
Opposition runs scored divided by overs
HOWEVER nothing is ever simple, there are key exceptions to that calculation.
What are the exemptions?
If a game is abandoned without a result the NRR scores / overs calculations are not included for either side, an example is -
NRR calculation for the game - Golborne 0/0 - Swinton Moorside 0/0
Insufficient overs were bowled in the 2nd innings to give a result.
Where a first innings is restricted for weather during the innings then the runs for NRR is the Revised Target for innings 2 (-1) and the overs is the full allocation, an example is -
NRR calculation for the game - Hadfield St Andrews 341/50 - Dukinfield 171/30
- This game ended at 30 overs of innings 2 due to weather and because this is over 20 overs then DLS comes into play and there is a result so NRR is calculated as above.
- Had Dukinfield been able to face their full 46 overs their NRR would be their score/46
Where a first innings is not restricted for weather during the innings and the team batting first is all out, then the NRR calculation for the 1st innings is the runs scored/overs available, an example is -
NRR calculation for the game - Austerlands 65/50 - Droylsden 66/11.83 (11.83=11.5 overs)
- Austerlands batting first had 50 overs at their disposal so this is used in the calculation.
- Droylsden could not bat for 50 overs as the game ended at 11.5
If this game had been reduced to 38 overs before the start then the NRR numbers would be-
Austerlands 65/38 - Droylsden 66/11.83
NRR calculation for the game - Worsley 268/50 - Glodwick 69/38
- The first innings was reduced to 46 overs during the innings so the revised target is used. In this case the Revised target was the same - 268 and 50 overs used as in example 2 above.
- The second innings was reduced to 38 just after the start of the second innings so this has no impact on the 1st innings NRR. Although Glodwick only faced 28.3, they were all out so, could have faced 38, so 38 is used.
NRR is only maintained as a cumulative total, with the calculations done automatically in the system.
