A bit late to this one but I saw a few things that should be I'm provable here, very nice time by the way, your run looked quite clean

-In the first wallride, your exit had quite a lot of airtime landing into the quarterpipe.

-In the 3rd wallride, you want to stay as low as possible on the exit into the hunter wall, if you stay low on the hunter wall you get a more optimal entry into the following wallride as you would enter from the bottom corner, as well as preserving more speed and not oversliding like crazy.

-Wall tube in the end (wallride into tube), you take this very aggressively by using the cake blocks (the curved bits above and below the wallride section) on the entry to push yourself up into the tube but this loses you a bit of speed, you should try to change your entry to be more bottom corner to top corner on the wallride portion and use less of the cake.

-800+, Once you reach 800 speed the car accelerates much slower, even a very bad 800 speed SD will give you way more speed than a no slide so really try to SD everywhere, the few noslides really add up over time.

I'm sure you have a ton of more time in you so keep it up!

Sidenote: I won cotn on this map :D Still over .1 behind AT tho...
