WTH, I’ll give it a shot…
You’re very smooth and you’re obviously lapping pretty fast judging by the fact that you pass more than you get passed.
As speeds got higher, you started turning in earlier in 3 and 10, but that’s common. You had a couple of laps where you hit it nearly perfect. Work on getting that consistently. Then work on bumping up your entry speed.
It may help to focus more on looking down the track at where you want to exit rather than on where you should turn in. I think in 3, you can look toward the concrete barrier on the far side of the track. As you get further into the turn, start looking down toward the flagger bucket on track left. For 9, the track-out is about 3/4 of the way down the left side curb. Get your eyes up and look for it as you’re exiting 8. Look toward the flagger bucket up the hill as you turn in. With 10 you’ll also want to track out fully at about 3/4 of the way down the left side curbing. If you find you’re reaching those track-out points too easily, it’s time to bump up your entry speed.
In the carousel, it’s not necessary to go all the way out to the curbing. Leave about 3/4 of a car width; a slightly tighter line. Use the carousel to play with the car a little. Try different lines. Try little trailbraking oversteer through 5, a little lift-throttle oversteer in the entry to 6, a little drifting in 7. Of course, don’t do this in traffic.
When you’re passing another car that won’t lift to let you back onto the ‘normal’ line, don’t hang yourself out to dry so much. Leave a half a car width between your line and their’s, but don’t go to the extreme opposite side of the track. You can still create a decent line from 3/4 of the way across the track and you won’t sacrifice as much exit speed.
Your line from 3 through 5 is perfect. I like that you aren’t influenced by the bad line of the cars in front of you.
Good job overall.
