Average speed camera distances / paired?

I was driving today on the A13 and not sure if I got away with a NIP from the average speed cameras. I got on the A13 at Prince Regent heading westbound, I got off at the second exit (not Canning Town, but the exit for the Blackwall Tunnel). There was 1 average speed camera pointing towards me when I was joining the A13 at Prince Regent. The next set of ‘3’ average speed cameras were just before the Canning Town exit. I was doing an average of 60mph the whole time and the speed limit is 50mph. My questions are: 1) I understand average speed cameras are paired - so as I got on at Prince Regent, and left very shortly after at the second exit, are these two set of cameras likely to be paired together? Or do they normally stretch over 2+ miles at least? 2) Is it likely for an entry camera (when joining the A13) to work with a exit camera at the next set of cameras on the A13? 3) Where are the entry cameras normally paired to when joining a dual carriageway with average speed cameras?

I understand average speed cameras are paired. REALLY that is how they work? you KNOW that or are just guessing? The average speed cameras over the lanes are not for issuing speeding tickets. they measure the speed of cars passing that point. They are for the use of traffic control to monitor for things like a traffic accident slowing the flow of traffic. The cameras of concern for a speeding ticket are the camera that times your entrance to the road and then the camera that that times your exit from the road at some other place. It is simple math to figure out the shortest time that it can be legally done. Do it faster then you can expect a ticket. Measured from Entrance point to your exit point. NOT EVERY INCH along the way. Just a little hint. the camera needs to see your number plate getting on and off. They do not register 100% of all vehicles that pass. If you are concerned about getting a ticket then just stop speeding.Over your time on the road you saved maybe 12 seconds.or less.for your mile on the road. Was it worth it?
