I'm struggling in the final sector. There are basically four turns if I don't count the final bend leading onto the S/F straight.
There are couple of different ways to take them. Every time you maximize speed through one of them you sacrifice speed for the next one.
My current typical slow s3 (and I'm not happy with it) turn by turn description is:
way too slow but great exit line - woooo, look at me go fast - OMG, understeeeeeeeer, OMG, make it stop! - ugh, I scrubbed too much speed in turn 3 AND I'm stuck with bad entry for the last one.
Obviously the compromise approach is there to just go slower in all the turns and get the best line possible but I don't think it's the fastest.
Here is what I would like to do instead:
on the edge with compromised exit line - mow some grass and sacrifice speed for wide entry for the next one - fast and smooth going uphill - wide entry, get all the braking and turning done early, carry good speed and start accelerating as early as possible.
