Yes I've been grinding this on and off for 6 years and when I was streaming it and mxf also couldn't tell me what I was doing wrong, since I timed every input on the correct frame, I was about to just give up forever. However a bit later I thought again about how sick it would be to end the comp with this star. So I tried to analyze the existing videos again and I noticed we do everything on the same frame, except for opening the box. I kinda noticed that before, but I started to mess around again and after a while I got 6.06 by holding straight up on a certain frame before reaching the box. I have no idea why or how that's possible, since holding up should just lose distance. I tried to get 6.06 from a previous savestate and after some more practice I got it twice from there. I struggled A LOT with getting the pc, walk, jump on the right frame during practice that session, but I was able to get this after just a handful of attempts. I guess with my current knowledge I could get this again in less than 30 min, but man this has been a journey...
