With a runway of 5 tiles (open end) in the other room, the ideal timing for the stutter is to release forward for 5 frames, and repress forward on the last possible frame before the transition. Other timings can work, but will gain the shinecharge further from the door, leaving fewer shinecharge frames remaining. After gaining the shinecharge, continue holding forward in order to make Samus stand. Then turnaround spin jump back toward the door, and shoot it open, making the Sciser fall; spin jump over the Sciser to reach the transition with a shinecharge.
