On Abyss, I specifically take it slow.

If you fall off the top there you end up having to take a very long route that circles around the skirt of the floating platform.

Even though I could hit it faster and use slide I just don't...

The risk of messing up that one turn is just too high to do anything else than slow down to the right speed.

You have to limit FPS and do slide turns. These levels instantly become playable from borderline impossible. That's just how game physics behaves
