hero, the idea is about this place:

Edit: Btw, just out of curiosity, when going for the first Reserve Tank, next to the First Super Missile Pack, did anyone ever tested if it's slower to get the Reserve Tank first and then go for the two Missile Packs behind it?
Edit 2: Managed to improve the Maridia Route Change a bit:
Damage boosting from the falling crab makes possible to land more to the right without loosing time, so you can get more speed for the mockball saving some frames. If you shoot the pirate while samus is falling, he will turn to the right, getting closer to the ledge you have to land, so when you damage boost samus reach the ledge faster.

Edit 3: Managed to improve it a bit more using a morph and unmorph to damage boost some frames earlier and Samus landed in a better position to start running. Also tried minimizing the most i could the lag during door transition, positioning samus more to the left in a way that it wouldn't change anything in the in-game time. I used Cpadolf's run to compare the times between the routes and the upper route seems to be around 35/40 in-game frames faster till now and looks much better. Probably still improvable.
