I suppose part of it will come down to the133mph, was this the highest speed you reached or the speed they are going to report you for. If it was a speed trap I guess the figures will be the same.
When I was done last May my highest speed was 128mph, yet, when the wrote me up they did me for an average 102mph over the distance and I got points and a fine. Guess I was still lucky getting points as I was over the 97mph cut off point.
