Ok this will be kinda long. It's possible to fall into the gap between the spinner and the ground near the end of the level and have the spinner launch you up into the finish line. I've been able to get this to happen as a proof of concept before but I haven't yet gotten it in an actual level run. There are 2 ways you can fall into the spinner: Option 1 is where you just run into the spinner and hope it deflects you into the gap. This only saves around 1-2 seconds but is less risky than option 2. Option 2 is where you intentionally fall backward and crash on the edge of the ramp and have your momentum carry you forward, hopefully into the gap below. This saves around 2-3 seconds. Once you're in the gap there is no guarantee you will even reach the finish line though, as often you will hit the corner of the metal part above or just not have enough power to get high enough. I'm going to keep doing attempts for this, but I wanted to share this as hopefully someone will be able to pull it off and get a good time.

Theoretically using option 2 sub 17 could be possible

this is what I understand skip. that's why i love the poki version

Well that's what UnsaidPanda did in his sub 20 run

No panda didn't do that win his sub-20 run

Can you make a video reference because I am a bit confused

The gap is between the front of the spinner and the ground, and it goes all the way to the other side near the elevator, that's how it can launch you into the finish line. The goal is the land inside of the gap below the ramp part in between the ground and the spinner.
