Put some time in and got:

I agree that the last uphill left-hander before the start/finish is v. important - you could easily lose .4+ seconds by taking it too cautiously, as I did on the above lap. But I'm amazed that hotboi (and others probably) can cross the line at 115km/h, the highest I've managed is 111km/h a couple of times, but it's usually about 107 at best, and I can never keep the RPMs above 5500 in third.
For the end of a hotlap, is everyone tapping the brake before that last corner or just letting off the throttle? I use the brake, but that might be because I always lose my nerve there.
The other key section is obviously the tight twisty section after T2, but i think that's beyond explanation - you just have to "use the force".
