This guide describes how to handle One Day or Twenty20 matches that are reduced due to bad weather. It covers adjusting the number of overs and calculating a revised target using the Duckworth-Lewis-Stern (DLS) method.
Since interruptions can occur at any stage, the guide is structured as follows:
- Pre-match adjustments
- First innings adjustments
- Innings break adjustments
- Second innings adjustments
- Match termination procedures
Although an appointed DLS Manager may handle official calculations, scorers and analysts must both correctly enter reduced match data to ensure the following:
- Accurate Power Play recalculations to ensure that Stats Wizard data for these periods is correct.
- Correct WASP (Winning and Score Projection) calculations, as displayed in the Score Summary.
- Precise Player Impact measurements, as displayed in the View > Stats and Graphs menu.
- Properly updated Overs Remaining, Runs Required, and Run Rate Required, as displayed in the Score Summary.
- Reliable Match Centre (e.g., http://live.nvplay.com/icc) and Web Portal (http://icc.nvplay.com) data, and information under Scorecard > Innings Notes.
It is important that both scorers and analysts enter the reduced match data as this data is not shared between them, even when both are connected via the internet. It is especially important that the Live Scorer update this information, as it is this that will display on the Match Centres and Web Portal.
Reduced match data also automatically creates an Innings Note (View > Scoring Entry) as either Match reduced to X overs (first innings) or Target revised to Y off Z overs (second innings).
1. Pre-match adjustments
If the match is reduced before the toss:
- Go to Scoring > Revised Overs/Target/DLS. The Revised Overs/Targets/DLS dialogue opens.
- Tick the Auto-update using DLS box if it is not already.
- Select the correct DLS option (for example, Professional 2018, v3) from the dropdown menu.
- Click Add to create a Pre-Start break.
- Double-click the Revised Overs field, enter the new reduced overs number (e.g., 40), and click OK.
- If further reductions occur before play starts, repeat these steps.
If overs are reduced before play starts, the DLS system is not yet required, as there is no revised target.
2. First innings adjustments
If the match is interrupted during the first innings:
- Go to Scoring > Revised Overs/Target/DLS or click on Overs Rem(aining) in the Score Summary panel. The Revised Overs/Targets/DLS dialogue opens.
- Click Add to create a new entry on the Revision History list.
- The system will auto-fill the current:
- Innings (1)
- Over/Ball (e.g., 0.6)
- Score at interruption (e.g., 6/1)
- Revised Overs (e.g., 40)
- Double-click Revised Overs, enter the updated number (e.g., 32), and click OK.
- If multiple interruptions reduce overs further, repeat this process.
You must enter interruptions before play resumes to ensure accurate Over/Ball and Score tracking.
3. Innings break adjustments
During the innings break, the Revised Overs/Target/DLS dialogue (Scoring > Revised Overs/Target/DLS) will add a link to the DLS Par Table:
- Go to Scoring > Revised Overs/Target/DLS. The Revised Overs/Targets/DLS dialogue opens.
- Click DLS Par Table link in the bottom-left corner of the dialogue.
- Review the Par Score Table:
- Displays Revised Target (e.g., last Par Score +1 Run → 159+1 = 160).
- This table can be viewed as Over-by-Over or Ball-by-Ball using the radio buttons.
- Print Options are: Print, Save as PDF, or Email as PDF (although the Match Referee should provide the official printout).
- If bad weather further reduces overs during the break:
- Open the Revised Overs/Target/DLS dialogue (Scoring > Revised Overs/Target/DLS).
- Click Add to log the interruption.
- Adjust the Revised Overs and confirm the new target.
- When starting the next innings (Next Innings is clicked), the Revised Target prompt appears.
- Click Edit Revised Overs/Target to reopen the Revised Overs/Target/DLS dialogue if further reductions occur.
- Adjust the Revised Overs and let the target auto-update.
4. Second innings adjustments

- Go to Scoring > Revised Overs/Target/DLS. The Revised Overs/Targets/DLS dialogue opens.
- Click Add to log the interruption.
- Adjust the Revised Overs.
- The Revised Target will update automatically.
For multiple interruptions, repeat the process after each delay.
5. Match termination procedures
If play is terminated after the team batting second has faced the minimum overs for a result:
- Go to Scoring > Revised Overs/Target/DLS. The Revised Overs/Targets/DLS dialogue opens.
- Click Add to log the final interruption.
- Adjust the Revised Overs (include the number of balls bowled in the incomplete over).
- Click OK.
At this point:

- The Edit Match Result/Points dialogue will open immediately.
