Hi, can anyone explain the safespot trick on Boundary of Life and Death? I've captured the spell several times with the trick, but my failures way outnumber my successes. Most of my captures don't even have a full safespot, I still have to wiggle a bit.
Using SakuyaA, I keep to Yukari's left until the third wave starts (the red bubbles), and then I try to find a safespot just left of the boss marker -- it's the only place I've ever found a safespot, and it's what I've seen on YouTube and in replays. However, the bubbles usually go through there, forcing me far left of Yukari, which makes it harder to dodge and I've never found a safespot there. Am I doing something wrong? How do you guys do it? (If I could find the right place to be relative to Yukari when the bubbles start, I think I could misdirect them, only I'm gotten inconsistent results doing that.)
Also, I read that the last few waves of bullets aren't aimed at you, and that if you stay still they go around you, but that isn't always the case for me. Sometimes the yellow/blue orbs aim right at me when neither Yukari or I moved, and once the fast butterflies did the same. And even when we're absolutely still, sometimes the orbs or the diamond bullets (first wave) will randomly shift and hit me in my safespot. Does anyone else get these problems?

Finally, is the spell entirely static according to your and Yukari's positions, and can someone actually safespot it every time? Is this trick even a safespot, or just a way to minimize dodging?
Any help would be great
