Embarrassingly I could do with a bit of legal advice...
A few weeks ago, I got caught exceeding the limit in a 50... I had forgotten it wasn't a 60 if I'm honest, and had been riding defensively to protect myself from the weekend warrior out to prove a point on his Ducati 1098 (couldn't keep up with me on the bends ironically, but sailed past me on double white lines on a straight road literally just before the point where I got clocked speeding).
I got sent this...

I admitted I was riding the bike of course, and then got sent this...

Nowhere does it say how fast I was actually going. Truth being told, I know I was exceeding 50mph, but honestly don't know by how much. I would be surprised if it was by more than 10mph anyway... I had forgotten it was a 50 but was genuinely more concerned for the fact an idiot on a Ducati had just gone blasting past on a solid white line...
The other concern is that nowhere does it state to offer me a speed awareness course (It was 12 years ago I last went on one). I thought that they always did this as an alternative to 3pts for anyone with a clean license...?
Any help/advice appreciated.
