Point Systems
Checks & Balances
These systems are used to calculate the Net Run Rate, decide in cases of Ties and for preventing those above from being implemented.
Net Run Rate
Net Run Rate Explained
Net run rate has become the preferred method of breaking ties in multi-team one day tournaments. It is often misunderstood, but really quite simple to understand.
A team's net run rate is calculated by deducting from the average runs per over scored by that team, the average runs per over scored against that team.
In the event of a team being all out in less than its full quota of overs, the calculation of its net run rate shall be based on the full quota of overs to which it would have been entitled and not on the number of overs in which the team was dismissed.
Let's take as an example Team A net run-rate.
| P | W | L | NR | T | Pts | Net-RR | For | Against | |
|---|---|---|---|---|---|---|---|---|---|
| Team A | 3 | 3 | - | - | - | 6 | +1.776 | 360/73.2 | 235/75 |
The columns we are looking at here are the last three: "Net-RR", "For" and "Against". The figure in the "Net-RR" column is achieved by subtracting the answer of the division in the "Against" column from the answer to the division in the "For" column.
To use this example:
FOR
Team A have scored, so far:
- Against Team B, 120 runs (for 6 wkts) from 25 overs
- Against Team C, 101 runs (for 9 wkts) from 25 overs
- Against Team D, 139 runs (for 7 wkts) from 23.2 overs
Across the three games, Team A scored 360 runs in a total of 73 overs and 2 balls (actually 73.333 overs), a rate of 360/73.333 or 4.909 rpo.
AGAINST
Teams opposing Team A have scored:
- Team B , 89 (for 5 wkts) from 25 overs.
- Team C , 71 all out from 24.3 overs.
- Team D , 75 all out from 21 overs.
In the case of Team C and Team D, because they were all out before their allotted 25 overs expired, the run rate is calculated as if they had scored their runs over the full 25 overs.
Therefore, the run-rate scored against Team A across the first three games is calculated on the basis of 235 runs in a total of 25 + 25 +25 = 75 overs, a rate of 235/75 or 3.133 rpo.
NET-RR
The net run-rate is, therefore,
4.602 Run-rate for
3.107 Run-rate against
