FAQ

Questions about the tools

01 Are the calculators official?
They are teaching and club tools. For a result that has to stand, use the method your competition names, such as the official DLS tool.
02 Do the calculators save my numbers?
No. They work in the page and forget the numbers when you leave. The match book in CricSport is where the record lives.
03 Can I use a calculator during a live match?
Yes. Enter the figures from the book, then check the result against the match centre before you share it.
