Shoot to the Island in the Sky 14.13 (-4f) [SM64] [TAS] [Scattershot]

TLDR -1f to tree, -3f post tree. While the elevator cycle makes it seem like it's not possible to get to the tree faster, you can still improve it because the final couple frames of the last elevator BLJ have a ySpd higher than 10 (speed of the elevator). Compared to Plush you have to get to the elevator 2f faster to save 1f, and 5f faster to save 2f (and this would truly be maxed without other tricks). Naturally I saved 4f and spent several days failing to get 5, so in the end I only got -1f to the tree. The part after the tree is much more interesting. Scattershot uses an aerial slidekick and a slidekick slide to steep jump dive transition that's possible on steep surfaces (I had never considered this, might not ever have even seen this). This gives you much more ySpd and gets you on the island much faster, albeit a lot further from the star box. Luckily with a grind the greater distance is not a dealbreaker since the original run used backward movement (which was probably optimal that close to the box). In the end this saved 3f from the tree to star grab. Towards the end I was also thinking about a PU route for this star (should have occured to me earlier), but I kind of doubt it's possible since there is very little time to build up enough speed and perform the PU movement and overflow jump. I also figured if it were possible it would have been done already. Note that the elevator save also saves 1f for Big Bob-omb on the Summit, I will upload a vid of this later so as not to overshadow this (much more interesting) run.
