This strat is a little slower than the normal springball strat for skipping SA-X, but I'm submitting it here just in case anyone is looking for an (in my opinion) easier strat for skipping SA-X.

Instructions from the video description:

The video shows the two most common outcomes of using this strat: either you have to spring ball jump over one beam, or three beams. It depends whether you get the morph ball bounce or not. Sometimes you'll get something inbetween if you're slow to move left, but you should never die if you get the first part of the strat.

How to do it:

• Start running right the moment you fall into the room
• Be sure to break both blocks (if you only hit the far right one, don't worry; just hit the other as you're falling)
• Shoot one beam in the direction of SA-X (doesn't matter if it hits or not)
• Run right
• Jump right as she's about to shoot her beam, and HOLD A for the entirety of the jump (the idea is that you want to jump as high as possible, feel free to let go once you start going down)
• Do a small wall jump past her as soon as she is just about to end her turn around animation. It's recommended you find a good visual cue for this: either aim for a specific spot, or look at what SA-X does.
• Morph and hold left. If you get the morph ball bounce, you have to jump over three beams (which is very easy); if you don't, you should be able to go fast enough that you only have to jump one beam.
