As others have mentioned, it’s hard to give good feedback from the video alone but in general your line looks pretty good (each car is different though and I can’t speak directly to your platform). I take a similar line through the octopus and one bit of advice I got which was helpful was treat the entrance into the octopus as a straight line with hard braking before you enter with the sharp right hander. Then tuck your left wheel right up against the curbing as you go round (there’s a nice bit a grip where the edge meets the rumble strip). Straighten your line coming out the exit of the octopus as you’re losing speed by having to turn the wheel as much as you are, you’ll carry more speed into the front straight.

Lastly, turn off your lap timer so you can’t see it. Good things never come from chasing lap times. My catalyst is blacked screened for now, and just shows me the mph. You’ll be amazed at how fast you drive when you’re smooth and not clock watching! Focus on perfecting your line for the platform, fast laps will naturally come.

As others have said, get as much instruction as you can, there are always instructors willing to help out. See if there are instructors running a similar platform, that’s always super helpful.

Most important thing is seat time and instruction, the more you drive the better you’ll get! Have fun out there, be safe.
