Seriously, if you can't ride faster than a 50bhp Ducati twin, with a novice racer on board in the inter group - then you should be in the slow group, and very embarrassed!!!
I'm now going in the fast group at Donington, BUT, I'm as dangerous to the really fast guys in the fast group as you percieve me to be in the inters. It's much safer for a 'racer' on a slow bike, to go in the inter group.
