What is Duckworth Lewis Stern (DLS) and why is it used?

DLS is a method of setting a revised target score in cricket for the team batting second, when overs have been lost due to a suspension in play. This half day course aims to unlock the mystery of DLS and to explain about the two different forms (Professional and Standard) that are used. During the course you will try your hand at calculating DLS using both methods.

DLS Professional is calculated using software, for which you will require a laptop running the Windows ® operating system (v7 or later). You will need to bring your own laptop but the DLS software will be provided on the day. DLS Professional requires the latest version of Java (Java Runtime Environment), which you can download at no cost from the Java website. Please ensure Java is downloaded and installed before attending the course. If you cannot bring a Windows ® based laptop, you can be paired with someone else to during the Professional exercises.

We will be calculating DLS Standard manually. You will find the use of a calculator helpful and be prepared for lots of maths
