In this video, I show an exploit that Hazel and I theorized about. This uses how the game handles speed cap to get more forward speed, which saves a significant amount of time depending on your speed.

PS: I editted my forward speed to the highest possible value for proof of concept. In a real TAS, the difference wouldn't be so huge but it'd be considerable.
Btw... shoutouts to pannenkoek
Enjoy!
