It was really hopeless. At least half the balls got impossible readings (e.g. 10kph or 190kph), and even the more realistic readings ranged between 75kph and over 120kph. My brother could hardly crack 50kph, and he is 14 and really not *that* slow. Whenever I tried to bowl spinners I kept on bowling in the 30s, even when pushing them through quite flat, although sometimes out of the blue they would be in the 60s and 70s which seemed more realistic. Overall I've learnt nothing and am left wondering what exactly the point is.

what does it measure? The ones they use on televised cricket is the speed out of the hand, but the ball slows down in the air and especially off the pitch, so it looks alot quicker than it is when it reaches the batsman. As bowlers run ups and bowling actions are so repetetive, there isn't a huge range with this unless the bowler actually tries to change the pace. I don't really know how it works, but I'd guess that your ball measures the average speed over such a distance, so as each ball is different, you'll get a fair range of speeds coming up and at a generally slower speed than the measurements you see professionals get. Although it going to such extremes is pretty odd, but who's going to put really expensive and accurate technology in summat that's going to get hurled around, thus has a fair chance of being broken?
