Did the sneaky S.O.B scamera get me?

So, I was driving home today on the A49 from Whitchurch north to Tarporley. As its a nice, wide, smooth and flowing road, and the weather was dry and sunny, I was driving to the conditions and making progress nudging the speed limit.
As I was actually concentrating on the road and driving smoothly, not fixated on my dashboard, I may have gone a few mph over the limit once or twice when accelerating out of corners or up inclines. To this end, I crested the brow of a hill on a perfectly straight stretch to see a mobile scamera van nestled on the leeside with the cameras out - I immediately glanced down and saw that I was doing an indicated 67-68, having accelerated to maintain momentum. I'll hold my hands up to that one because, as said, I was actually looking where I was going instead.....

.....anyway, my question is - given that a indicated 68 is likely to be 64-65, which is within 10% of 60, can I expect a ticket or have I escaped by the skin of my teeth? How strict are the scamera vans - do they operate to gatso tolerances or are they manned by "OMG speed kills think of the children" types?

I have so far managed 5 years of driving with a clean licence and I have no desire to get points now....

No letter recieved as yet, so I think I must have been just under the + 10 % threshold when allowing for speedo overread
