Reminder – new method of calculating target scores in limited overs matches this season

With the Gabba T20 series starting this evening, a strong chance of showers and a round of one day matches in Reserve, Third and Fourth grade, this is just a reminder that there is a new method of calculating target scores in limited overs matches this season.

Last season all limited overs competitions used the Duckworth-Lewis method, but this season, calculations need to be done using the Discounted Total Runs method.

Captains and scorers should download the worksheet from the link below and print out several copies to keep with your scorebooks. Also print out the sample completed worksheet as an aid in using the method for the first time.

The principle behind the method is that when the chasing team loses overs due to interruptions, the score of the team batting first is reduced by their lowest scoring overs first. That is, if one over is lost to rain, then the lowest scoring over of the first team (which could be a maiden) is taken from the target score.

The target is also discounted by a set percentage for each over lost, which for this season is 1% per over for all grades and formats. This balances the calculation for both teams. Without the discount, the method would favour the team batting first due to including their highest scoring overs in the target score.


The worksheet has two tables. In the first table, scorers to record the number of runs scored per over of the innings.This allows the scorer to re-order the overs from the highest scoring to the lowest scoring overs.

After completing the first half of the form:

  1. Add the 15 highest scoring overs (or 5 highest scoring overs for Twenty20 matches) and put that figure in the Runs column of the ’15’ row. We start here as the match is incomplete if 15 overs per innings (or 5 in T20) aren’t possible.
  2. Multiply by the percentage shown and put that figure in the DTR column
  3. Add the 16th highest scoring over (or 6th highest scoring over for Twenty20 matches), multiply by the percentage shown and put that in the DTR column.
  4. Repeat step three for every over scheduled for the match.

Once the second table on the worksheet is complete, scorers will have a target score for every potential number of overs in the second innings. The figure in the DTR column is a tied score, 1 (or more runs) is required for a winning score to be achieved.
