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).

So, today all bright eyed and bushy tailed I go out on to the paddock with 2 cameras with the intention of showing off my new much faster approach and guess what happens? Yep you guessed, if the stumps had been barn doors I'd have struggled to hit them! I then tried a Terry Jenner approach - same load of tat and then my usual approach another bunch of tat.
