The best of skips. Near the end, in the single-box gravity room, it's possible to position the box in such a way where it gives the box a lot of momentum to the right just by hitting the floor. By doing so, the box will be off to the right side of the room instead of the left. This skips having to push the box to the right for a gravity cycle.This results in activating gravity only twice in the room in a 9 egg run. If the skip is failed, it just requires pushing the box to the right for a gravity cycle, which is the regular strategy anyway.
Saves about 10 seconds.
