requirements. For instance, cricket authorities often require information about matters such as the rate at which teams bowled their overs. The media also ask to be notified of records, statistics and averages. For many important matches, unofficial scorers keep tally for the broadcast commentators and newspaper journalists allowing the official scorers to concentrate undisturbed. In the English county game, the scorers also keep score on a computer that updates a central server, to meet the demands of the online press that scores should be as up-to-date as possible. The official scorers occasionally make mistakes, but unlike umpires' mistakes these may be corrected after the event. Some cricket statisticians who keep score unofficially for the printed and broadcast media have become quite famous, for instance Bill Frindall, who scored for the BBC radio commentary team from 1966 to 2008, and Jo King. The ECB's Association of Cricket Officials provides training for scorers. Methods of scoring There are predominantly two methods that scorers use to record a game: manually and computerised. The manual method uses a scorecard and a pen. The scorecard is colloquially known as The Book. Using the book, the scorer fills out two main sections per ball, the bowling analysis and the batting analysis. Each section helps track the number of balls bowled in an over, any extras (such as Wide Balls and No Balls) and also any wickets (or dismissals). At the end of each over, the scorer may fill in an over analysis with the score at the end of the over, the number of wickets that have fallen, any penalties incurred and the number of the bowler in the analysis. Most software used for cricket scoring uses a form at the front end with buttons for the scorer to press to record ball by ball events. Additional functions include being able to draw a line denoting where the ball went from the batting crease and where the ball pitched. This gives additional charts tracking bowling placement and shot selection which can then be used at the coaching level. This additional information, however, does not form part of the critical role of a scorer, which is to keep track of the score of the game. It has been known for scorers to use both methods in conjunction with one another, in case the computer goes down or runs out of battery. In addition to PC software, mobile
