Ok, skipping to the punchline - short answer is - wait 14 days + a couple for the fine/ticket to be posted, and you'll know if you've been done or not.
So, for the story behind the punchline... coming home from visiting my girlfriend's brother, and I'm going down a wide road about to emerge from a town and slowly accelerating, along with the flow of traffic - I'm two seconds behind the car in front, and likewise the cars behind me. I see a 40mph sign ahead, this provokes me to think 'hang on, is this a 30 or a 40mph?' with that my girlfriend says 'cameravan' - bugger! The cameravan is parked on the other side of the road, rear end facing me, big black window staring at me blankly and coldly like a Cyberman. I
think I was doing indicated 38mph (though she disagrees and says more like 32mph, so I may well have been slower than 38) By the time either of us saw it I'd say if my speed had been read it was a couple of dozen yards back - so in theory I wasn't going as fast then.
Knowing the definition of 'speeding' is ... your speed + 10% + 2mph, that means in theory you can do 35mph - but taking into account my speedo definitely over-reads, by about 2-3 mph at 30mph, that means at an indicated 38mph I could be doing 35mph. So borderline.

I've no points, NCD, trying for a clean licence, and really can't afford my insurance doubling (I've already done an online quotation with a theoretical 3 points and it made me wince)
So my question is - are they...
a) trying to get people coming out of town, like me accelerating up to 40mph, in a 30, only about 20 yards shy of a 40mph sign... or
b) are they trying to get Sunday bikers etc... who are barrelling along the country roads doing 50mph+ in a 40, who then enter town, still doing 50-ish mph?
Are they there trying to act as deterrent, or get people who are literally 1mph above the threshhold?
Slightly worried, and it's praying on my mind, especially as I really am trying to be a good boy on the roads, and touch wood hope I am, for the most part.
