Analyst Instructions for Reduced Matches

This document provides detailed instructions for when One Day or Twenty20 matches are reduced due to bad weather, and a revised number of overs and (sometimes) a revised target is applied using the Duckworth-Lewis-Stern (DLS) method. As interruptions that cause a reduction in overs can occur at any time, the instructions follow the logical sequence of pre-match, first innings, innings break, second innings, and terminating a match.

Although the official DLS calculations will be undertaken by the appointed DLS Manager at formal matches, it is essential that both scorers and analysts enter the reduced match data, at the appropriate time(s) throughout a match, so that other key pieces of information and calculations are also correct for all online and at-venue viewers and all users, including coaches and players. This reduced match data will not only ensure that the correct DLS Revised Target is calculated, and thus the integrity of the match scorecard and result will be maintained, but also:

  • The number of revised overs in each Power Play is automatically recalculated, which will also ensure that Stats Wizard data for these periods is correct for in-match or post-match analysis
  • The WASP Projected Score (first innings) and Probability of Winning (second innings) calculations are correct, as displayed in Score Summary for both analysts (writers) and coaches (readers)
  • The Player Impact measures are automatically recalculated, again for both in-match and post-match assessment, as can be accessed via the View -> Stats and Graphs menu
  • The Overs Remaining (both innings), Runs Required, and Run Rate Required (second innings) calculations are correct in Score Summary, which is obviously essential during a live match
  • The Match Centres (e.g., and Web Portal ( are always correct with all these relevant pieces of information, including Scorecard -> Innings Notes

To reiterate, both scorers and analysts must enter the reduced match data because it is not shared between them, even when they are both connected via the internet. It is especially important that the Live Scorer maintains this information, as it is this that will display on the Match Centres and Web Portal.

All reduced match data entries will also automatically create an Innings Note (see the View -> Scoring Entry menu), displaying as either Match reduced to X overs (first innings) or Target revised to Y off Z overs (second innings), and should be entered after the relevant Play State break, e.g. Rain, Ground Delay, or Bad Light, once the revised number of overs per team has been confirmed by the umpires/referee.



If bad weather reduces the number of overs per team before the toss, go to Scoring and select Revised Overs/Target/DLS from the menu. On the dialog box that opens, check that the Auto-update using DLS checkbox is ticked and that the correct DLS (Professional 2018, v3) is selected in the dropdown:

Click the Add button to create a Pre-Start break in the Revision History list, double-click in the Revised Overs box, type in the new number of overs per team (40), and click OK:


If bad weather again reduces the number of overs per team, either before or after the toss (but before play starts), repeat the above steps. If the number of overs per team is only reduced before play begins the DLS system is not (yet) required, as there is no revised target.


First Innings

If play is interrupted during the first innings and the number of overs per team is reduced, either return to Scoring -> Revised Overs/Target/DLS or go to Score Summary and click on Overs Rem(aining) to re-open the dialog. Again, click Add to create a new entry on the Revision History list, which will automatically populate with the current Innings (1), Over/Ball (0.6), Score (6/1), and Revised Overs (40). As above, double-click in the new Revised Overs box, enter the updated number (32), and click OK:


The Innings, Over/Ball, and Score information at the time of any interruption that reduces the number of overs per team is crucial to the DLS method, which will now come into effect in the second innings to calculate the Revised Target. Thus, it is critical that these interruptions and Revised Overs are entered before play resumes, because the Over/Ball and Score will affect the Revised Target calculation. However, if this is not entered at the time, double-click in the Over/Ball box and select the correct Over/Ball and Score at the actual interruption/reduction from the dropdown list, and click OK.

If a second (and subsequent) interruption(s) during the first innings further reduces the number of overs per team, repeat this process so that the DLS Revised Target is correct at the end of the first innings.


Innings Break

After the first innings, the Revised Overs/Target/DLS dialog will display DLS Par Table at the bottom-left:


Click this to open the DLS Par Score Table for the current number of Revised Overs (27), with the Revised Target being the last Par Score (159) plus 1 Run (160):


The Par Score Table can be displayed in Over by Over or Ball by Ball format, and the dropdown button used to Print, Save to PDF, or Email as PDF (although the Match Referee will provide the official printout). If bad weather reduces the number of overs per team during the innings break, re-open the Revised Overs/Target/DLS dialog, Add another interruption, and update the Revised Overs as above:


When Next Innings is clicked to create the second innings, a Revised Target prompt will appear:


Clicking the Edit Revised Overs/Target button will re-open the Revised Overs/Target/DLS dialog, which may be required if another reduction occurs at this point, before play resumes after the innings break:


If so, update the Revised Overs as usual, and the adjacent Revised Target will automatically recalculate:



Second Innings

If play is again interrupted during the second innings (or for the first time during the second innings), re-open the Revised Overs/Target/DLS dialog and update the Revised Overs, as per normal:


Again, the Revised Target will automatically update, and as per the first innings repeat this process for each second innings interruption that further reduces the number of overs per team.


Match Termination

If play is terminated (i.e., after the team batting second has received the minimum number of overs to constitute a match, but before the revised maximum number of overs per team have been bowled) by rain, Add another interruption and update the Revised Overs (including the number of balls in the current over if play was terminated during an over) as usual, and click OK:

At this point, the normal End of Innings (and match) prompt will appear and clicking Yes will open the Edit Match Result/Points dialog. The Result Display with (DLS method) is automatically calculated, but confirm this before clicking Save to finish the match.


However, if this last interruption/reduction is not entered, and the second innings is ended by clicking Play State -> End of Innings -> End of Overs, it will be automatically added to the Revision History list on the Revised Overs/Target/DLS dialog, and the Edit Match Result/Points dialog will open immediately.
