This will likely be a TAS only trick, but I accidentally found a super-precise Level 6 trick that might make HIO possible.

There is a small 90-degree angle ridge on the first turn. By hitting this at the exact speed in the exact spot, it may be possible to shoot up into the air and get an HIO or land really close to the goal.

If done fast, this could save 1-4 seconds.

I'll link a video of what I mean in a bit.

Level 6 already has a hio, and it has been done by humans. I don't go for it because it is too hard for me to do.

which hole 6 or am I blind and it says.

nice double necropost

Link the video plz
