I didn't believe you at first as that struck me as a wide beam... but indeed, 3 milliradians at a distance of 504m give a beam width of about 1.5m.
However, that means it is only 75cm each side... I think that is well within the target if you are on or around the centre of the vehicle.
It does obviously depend very heavily on the video cross hairs being adjusted to match the laser that you can't see. I realise there is a procedure to do this - but how do we know that it has been done?
However, as you say, I wouldn't try and run that as a defence unless I had very deep pockets.
Checking the alignment should be noted somewhere, in the operating officers notebook possibly?However, that means it is only 75cm each side... I think that is well within the target if you are on or around the centre of the vehicle.

I had a play with one about 8-9 years ago, the range finding function means you can use the edge of an object to work out if the beam is centred in the crosshairs, I was three floors up so used a chimney stack on another building. Given the construction I think you would need to drop it to shift the alignment so most of the time it would just be a check without an adjustment.
Most people miss that a calibration is a bit like an MOT, it is the history that is important not the one off event, if an instrument needs significant adjustments or the correction parameters change between calibrations then there is more uncertainty in its accuracy.
......bruv.A good few years ago I was driving towards a speed van in a 30 limit. It’s a well known trap just down the road from where I live. I always stay below 30 as a matter of routine.
I was in a little 2 seater sports car and a big white van roared up aggressively behind me. Ha ha I thought serves him right.... he’ll get nicked.
10 days later I received a FPN for 36 in a 30. I wrote and asked for a photo. They sent me one showing my car with the white van literally a metre from my rear bumper.
I could do nothing but take the points. What could I prove? I still to this day believe that the radar picked up the van and not me.
My only FPN in 35 years of driving. Annoying and unjust I felt!
Sometimes we are just powerless against the machine and have to just take the easiest option.

Two different alignments here... one is the alignment of the sighting scope built-in to the LTi20-20, the other is aligning the LTi with the video recorder. As I understand it, as you say above, the alignment of the scope to the laser is pretty rugged and not likely to move unless seriously abused. The alignment of the video is different (maybe).Most people miss that a calibration is a bit like an MOT, it is the history that is important not the one off event, if an instrument needs significant adjustments or the correction parameters change between calibrations then there is more uncertainty in its accuracy.
None of this is going to help the OP - and as far as I can tell he admits the offence anyway, so my alignment question isn't relevant to this case.

Much as everyone is saying to the OP.... slim chance of success and costly. Easier and less risky to take the points and have done with it. I was less than impressed at the time and was convinced I wasn’t speeding.
Ever since that event I’ve been firmly of the view that speeding guns can be wrong.

How would you contest it though?
You are almost guilty by default (guilty until proven innocent in these cases remember as the machine can never be wrong ...). Secondly, if you dare to contest, you get a higher fine and / or points. Not much fun with those odds stacked against you to contest it.

OP, only one answer I'm afraid.

Unfortunately, I have a feeling it needs to be contemperaneous.

Rats, sounds like it was a fair cop, pretty sure we were all doing the same speed so guess its just my unlucky day!
Outside the boundaries for an awareness course, so looks like I'll have to suck it up, bet the guy in the Dub cant believe he hasn't received a letter yet!
probably just as well I want in this one as I'd be off to jail I'd imagine!

82/70 is usually a course. Why do you think it’s ‘outside the boundaries?’Outside the boundaries for an awareness course, so looks like I'll have to suck it up,
Here's an approach the OP could take - necessity? He's got a car clearly gaining on him significantly. If he admits 73/70 - after all, he did check his speed, and says he was only speeding to avoid the risk of being hit from behind... that just could work. Frankly though, an indicated 73 is probably under the limit.
