I think your bowling is over 40mph Dave, I think one that hits the stumps starting at around :52 is 43mph or so out of the hand.
I think I have a good method for getting the ball speed now. My method is this: slow down the video on youtube to 1/4 speed, then with a stopwatch measure the time from release to hitting the stumps. Then do the same for a spin bowler on TV where you are given the radar gun speed. Then your speed is approximately their speed * their time / your time. I think this should be accurate to within a few mph. If you are measuring a ball that hits the back of a net there is an adjustment to be made.
(one of my deliveries looks around 30mph... think I have a bit of speeding up to do).
