Don't move the marble at all, stay in front corner. Don't even jump.
It was actually tested a ton because the idea was for the player to do nothing and get flung and not have to do anything when he lands (so he doesn't go OOB on landing).
If you keep getting flung super high then something is messed up on your end and I don't know what. First time I hear of anyone having this probelm.
