trouble with videos, is the speedos arent 100% accurate at 100mph coul be 95mph or even 105???

But constant. If you've got a run on video, you can work out the absolute accuracy (using GPS or whatever) whenever you like...

my lcr is about 3 mph faster than the gps indicates

when driving an indicated 100mph my Road Angel 2 jumps between 97 and 98mph.

Thats a lot Allen, so an indicated 100 means you're actually doing 90mph?
You're still running standard wheels and tyre size's aren't you?
