Those were the two that I got wrong.
You can see that braking too early for the hairpin put me on the rumble strip, which limited the amount of throttle that I could use without suffering wheelspin. It's also pretty clear that I missed the turn-in point for the following corner. And when I did the final sector well, I used almost all of the right-hand curb in the first S-bend, and slowed down much less for the tighter right (you can see that I didn't use all of the track there). I was very happy with the first sector, though.
