Did you see it?
Rotation of the arm didn't really come into it - it was clear that at shoulder height, it was veth bent, and at release it was slightly bent.
yes i saw it...
it is really hard to explain with out actually showing you what I mean, it was what Dave Richardson was trying to say as well.
When Simon Hughes was showing those side on shots showing the arm angles, it did appear to show that the angle of bending in the arm decreased from the start of the action (arm at shoulder height) to the release of the ball.
But if you looked carefully, the arm also twisted, so if you can imagine the illusion of straightening could occur due to the fact that as the action takes place we are seeing (and therefore measuring angles) different parts of the arm.
In order to get an accurate picture of the angle of the arm through the action, the camera really needs to swing around towrds the front, following the twisting of the arm, so that the same 'face' of the arm is directed towards the camera, and I would guess if that was possible, the amount of straightening would be negligible..thats why Simon Hughes analysis was a bit too simplistic. (which as I say,Dave Richardson tried mentioning in his interview with Nicholas).
I know i probably havent explained it very well, but it is very hard to explain without showing what I mean
