ok so im gonna share my findings outside of a discord server
So Descole's jump height, right? He jumps extremely high, but I wanted to find out a rough estimate for shits and giggles. And Miracle Mask spoilers below.
(Also don't expect anything math-y or mattpat-style or anything, I threw realism out the window for this one and made a blender scene based off of screenshots)
So going into this, I realized that the background that I extracted and the background within the 3d cutscene didn't match up. Because of this, I relied on the closest background elements to at least line up Descole's starting position and tried to ignore the rest for now. (Thanks Slyzer for the playthrough!)
After getting Descole's most neutral position, I then went ahead to ""shrink"" him based off of the very first frame he's seen in midair. I'm not actually shrinking him, but it's similar because I'm putting him farther or closer depending on the scale.
That's how i ended up getting something like this in Blender, albeit it's pretty scuffed;
And one more thing, I decided to use Layton as a measure because he has an official height of 176cm (including the hat). So what answers did that provide?
Well for starters,,, He fucking FLEW.
And he does look pretty high. Like... Really high. So how high is it? After stacking some duplicated Laytons on top of each-other, I got just about...
FOUR LAYTONS (rounding up)
And because he was in a rapid descent within the first frame of airtime, we can assume that isn't his highest point, otherwise he would've been slow at the first frame and sped up as the descent continued.
So with that in mind, I added an extra Layton. Which leads us to...
