I was a bit confusied where to put this question finally i have decided in computer section. In Cricket
1. How does the speed of ball is mesured?
2. How does a pitch map of a bowler is maped?
3. How does a wagon wheel of a batsman/team is created?
4. How does the camera/software mesures the distence between bat and crease.

How to get the better of someone who thinks he knows everything about cricket! Ask him how many counties there are in the County Championship.
