- To authorize use of DLS calculator in the PlayHQ Scoring software to determine results in interrupted limited over matches.
SUMMARY OF CHANGES
- To make this change would mean adjustment of a few words in Regulation 33.4 and editing the calculation sheets for each of 4 competitions.
- It has been suggested that since the PlayHQ scoring software contains a DLS calculator that this may allow use of the DLS calculator.
- A DLS calculator has been available on the MyCricket Scoring app for several seasons. So this is not a new opportunity.
- The answers to questions of training, availability and suitability of scoring equipment and networks and practicality are not yet available.
- These questions are actually VERY complex, I think they require sophisticated modelling and demonstration before any commitment to DLS method is made.
- CCC have made use of DLS method to determine results in interrupted one dayers for the past two seasons. There have been no more than 50 one dayers out of 250 matches played in that time.
- But so far as I am aware NO matches have had occasion to use DLS yet. So there is no actual experience of DLS performance.
- My experience of umpiring CCC One Dayers (about 5 of 'em) suggests that most CCC teams are vastly underprepared to use DLS.
- Luckily there have been no rain breaks....
- I predict that if some matches were decided by DLS (say, a round of matches were curtailed by severe storms) then multiple results would be delayed for several days (at least) while disputed results were referred to the Management Committee (to report what happened?), results decided (how does DLS work?) and resolve all the arguments.
- The second time it happens might be easier....
The Wikipedia article on DLS is a window into the complexity of potential results e.g an interruption late in the first innings can lead to an increased run target in the second innings. Also which resources edition is being used and is there different compensations required for 20, 35, 40 and 50 over cricket or high scores.... even if an updated table of par scores for each remaining ball of the innings can be computed how do the batters or the fielding captain respond appropriately?
These are questions for which require clear answers before DLS is adopted.

| 33 RESULT OF THE MATCH For Saturday One Day 35 Over Matches/For Sunday 50 Over Matches/For Super 20 Matches/For Sunday Over 40’s – 40 Over Matches ... | This would need to be updated for 4 separate competitions. | 33 RESULT OF THE MATCH For Saturday One Day 35 Over Matches/For Sunday 50 Over Matches/For Super 20 Matches/For Sunday Over 40’s – 40 Over Matches ... |
33.4 In a match where the team batting second has not had the opportunity to bat for the target number of overs and has not been dismissed and has not passed its opponent’s score, the result will be decided on the average run rate throughout each innings. | - | 33.4 In a match where the team batting second has not had the opportunity to bat for the target number of overs and has not been dismissed and has not passed its opponent’s score, the result will be decided on by the Duckworth Lewis Stern method using the DLS calculator function in the PlayHQ scoring software.

33.5 For example: • Team A – scores 135 batting first (20 overs). • Average Run rate is 135/20 = 6.75 • Team B – has only 15 overs available as a result of an interruption to play. • Target score is 6.75 x 15 = 101.25. 101.25 runs rounded up = 102. • Team B requires 102 runs to win from 15 overs. 33.6 For example: • Team A – scores 120 batting first (20 overs) • Average Run Rate is 120/20 = 6.00 • Team B – batting second scores 89 not all out in 6.3 overs (rain stops play). • Average Run Rate is 89/(6+3/6) =.13.69 • Match is a draw because minimum overs not achieved. • To win Team B must face at least 10 overs and score more than 6.00 runs per over, or score more than other team’s score. • Note: When innings ends with a fraction of an over, the correct fraction will be used to calculate average run rate. | These examples would become redundant. | 33.5 NIL 33.6 NIL |
