The jump also lets you get the hitbox that links into the 2nd hit perfectly, even at like 150% the 2nd hit will land so long as you get the close hitbox of the 1st.
The reason why people struggle to land it, or the reason why people think they can DI it is mainlt due to MKs always wanting the tip of the 1st shuttle loop.
Basically this(by Ulevo)
1: Shuttle Loop 1 and Shuttle Launch 1 have two distinct hit boxes; the sweet spot and the sour spot. I had suspected this up until recently but never confirmed precisely how they worked. Shuttle Launch 1's sweet spot is right in front of Meta Knight as he leaves the ground. Shuttle Loop 1's sweet spot is the visual blade arc that is shown as he ascends, directly in front of Meta Knight, as well as in front and above. There is a star flash that happens when using Shuttle Loop 1. The sweet spot seems to end vertically just before that star flash. Shuttle Launch 1's sweet spot is a lot less defined and is much closer to Meta Knight's launch start position near the ground.
The sweet spot for both has high base knock back, and low knock back growth. To give you an idea of the kind of base knock back it has, if you take Sheik and bring her to Duck Hunt, bring her to the far left of the stage and then roll her to the right once, if you Shuttle Launch to the left and arc it forward so the 2nd hit misses, she will be launched high enough to land on the second tallest branch. If you repeat this at 150%, she will only go marginally higher, enough to reach the tallest branch. Shuttle Loop behaves in a very similar fashion. The base knock back and knock back growth as such that even as high as 200% or more, we will never miss the 2nd hit when sweet spotting as long as we arc correctly.
The sour spot has low base knock back, low knock back growth. However, the knock back growth on this is very important.Essentially there are two reasons we as players miss our Shuttle Loops. We hit the sweet spot and arc Shuttle Loop incorrectly in tandem with our opponents DI, or we hit the sour spot near the end of the hit box and they are past a certain %.To illustrate what I mean by the latter, take Sheik to Duck Hunt, put her on the fourth highest branch (left one), and roll Meta Knight towards the ledge. Do a short hop up air and buffer a Shuttle Loop. If done correctly, Meta Knight will be as low as possible to the ground while still doing a Shuttle Loop, not Shuttle Launch. This distance between Meta Knight and Sheik is approximately as far away as the opponent can be before Shuttle Loop 1 will begin missing. Up until 129, Shuttle Loop 2 will connect. After 130, Shuttle Loop 2 misses.
Essentially this is the % where a Meta Knight would need to adjust the timing of the move so that he goes for more than just the tip of Shuttle Loop 1 in order to secure a kill.
