Decided to post some small findings here.
WS Spiked Platforms Room:
--------------------------------
Used the pseudo screw to cancel the invencibility time after the first damage boost in the spiked room, so Samus can damage boost again earlier. If i calculated right the smv is 36 frames faster than the strategy used in the current 100% run, though health management could be a problem since i took one more damage from the spikes than Cpadolf took in his run.

Note: For this trick to work, Samus has to charge the beam before the first damage boost (or maybe just before the second) so she can use the pseudo screw to cancel invencibility.
WS Walljump:
----------------
This is more an update of the walljump strategy found by Kriole in the spiked platforms room going for the ET. I managed to get a damage boost that makes Samus land in the right spot in the next room, so you don't need to run in the water to jump up.

Under Charge ET Exit:
-------------------------
This one is just 1 frame in-game time faster and 3 realtime frames faster. My idea at first was to use the reverse walljump trick to jump up in highspeed, but unfortunatelly i got the walljump animation too close to the wall, so Samus touches it and loose her speed. So, although i used a reverse walljump here, i could have used a normal walljump and the result would be just the same.

Draygon's Eyed Door:
-------------------------
Managed to hit Draygon's eyed door 10 frames earlier.
smv
Note: I only used memory watch to keep an eye on the in-game timer to see if the strategy was faster or not, so the SMVs are not optimized.
Edit: Here is one that would probably save time but i couldn't make it work. Good luck.
