Sakes Harry.I understand precision and accuracy.
How much over 50 MPH do you have to be to constitute speeding?

HMG makes no such claims so in theory you could be done for doing 30.01 MPH in a 30 zone.
So, people of NSC, what is the smallest number of MPH over a limit that has triggered police action (fine or fine and points)? In my case at least 10% plus 2 mph.
As Hürzeler said wrt kicking balls away they're entirely different situations.
Yes most speed cameras are set at 10%+ 2. There isn't actually any reason for this except that when they put in the first generation cameras that had actual film that needed to be collected in they first set them at 5mph over and they ran out of film about 2 minutes later.
You've been done by average speed cameras. So firstly the time and distance are both relatively large so your calculated speed is incredibly accurate.
Secondly no allowance needs to be made that you could possibly be mid overtake or just briefly didn't notice your speed or whatever.
You drove for a considerable time above the speed limit, and given speedos usually read higher than your actual speed you probably saw 60 on your speedo and carried on.
