My walk though of a lap:
3rd through Hall Bends down to 2nd for the hairpin
short shift to 3rd for Barn then up 4th then 5th for the straight. braked down to 110 for Coppice and powered through keeping weight on the rear to stop it stepping out.
Changed to 4th then into Charlies 1 staying wide and straightening up and dabbing brakes and turning for apex of Charlies 2 to bring the front in better. (The cone was in the wrong place here)
Into 5th on Park straight and held power on over the crest braking just before surface change and down to 3rd for Park. (again the cone was in the wrong place here)
Short shift to 4th (no braking) for Chris Curve and accelerate through this and headed for the brown tarmac (hitting 100) and then on brakes and down to 3rd for Gooseneck. Over the apex of the first part and a really early apex for part 2 and basically head for the field
but just keeping it on track.
Into 4th down the hill before standing on the brakes, into 3rd and trailbraking right to the apex of Mansfield, then applying the power to stop the back coming round. Keeping right to cut across the curve, into 4th and head straight at the turn point for The Mountain.
Change down into 3rd and hug first apex and start applying power just after the apex and throw it into second part still on the power avoiding getting too close to the pesky cone things on the apex
Up over the hill in 3rd and hold up past the restaurant.
Someone timed a few of my laps in the afternoon and they were mid 1min 40's with varying levels of traffic. I am guessing your bike times would be way less than that
