Metroid Dread - Slightly Shorter Shinespark

As far as I can tell, you should not have enough space to get Speed Booster active here unless you do this. It seems that if you turn around just as you run into a wall and prime speed booster during the turnaround animation, it will activate just a little bit sooner, allowing a close-to-pixel-perfect speed booster in this part of the map. Samus seems to turn around during her wall-bump animation, and this appears to give you just a little more distance. Might be applicable to other places, I don't know.
