Yeah, I realize the rocket is safe. It was more that I'd move it too far and then wonder why the orb kept drifting up (or down). The orb doesn't move vertically very fast so it sometimes took a minute to realize that it was drifting instead of staying on the line where I thought I was. It was mostly in the 500-600s at times when I had the orb near the far right and was intensely focused on dodging between a bunch of closely spaced enemies.
