Dude that is awesome to know can't wait to see.
Also this might suck but pok3monrocks correctly noted that if you were to dodge roll to the switch on the second screen on day 26 rather than attack the switch Xigbar should teleport up before the cutscene triggers which means you don't have to wait for the heartless to despawn so while you hit the switch slower you make up for it (Unless you were manipulating for heart points).
Yo good work so far. I was just wondering on day 152 we were always wondering it it would be possible to skip the cutscene trigger in the graveyard if we had the heartless die as you were transitioning screens (Similar to the Abu skip on day 51). We ruled it out for single segment but it might be doable for the TAS.
Also if you can find an out of bounds for 255 maze then it might be possible to skip the first guard but we've never been able to find anything.
Hey I just found out this is still being updated. I don't know if this will effect you but we recently found out that the PAL version of 358/2 loses 1 minute to NTSC on the credits. However the PAL version saves around a minute+ to the NTSC version via text if you set the DS's language to Italian. We're still not 100% sure which is faster but it may be something to look into (Unless you want to keep the language in english in which case it doesn't really matter).
Keep up the work. I've managed to push the Re:Coded time down a long way because of your Re:Coded TAS so I hope to do the same with Days once you finish this. Also I can't wait to see Ruler of the Sky 0 cycle done.
Only a few things come down to luck in the grand scheme of things so its not the worst thing in the world to run :)
As for world order I still think Olympus will be your best first choice giving access to Omnislash and possibly Blizzard raid (You may be able to skip this since you won't be needing it for Dragon maleficent or Axel).
As well as Omnislash it will give you early access to Olympia which is a pretty powerful early game combo finisher and its best to consider how you will build your decks now rather than later.
Edit: Completely forgot about Retrograde which should make up for any CP loss since you are getting sleights
