So my FC recently started doing Levi (I know, it's old content) and I had an idea for dives, but I need to test it and see if the timing works. Presume head is NW and tail is NE:

Seems to me that if everyone gathers at north edge of the center circle right after Tidal Roar, you can wait for Levi to jump in the water, then as soon as puddles appear, start running south (like triple eruptions during Ifrit EX) with camera facing north.
If spout appears N(W), move slightly to the right and continue running south.
If spout appears N(E), move slightly to the left and continue running south.
If you don't see a N spout, he's popping to the E (but not E(S)), which means you just keep running straight south to the safe zone.
Then everyone gathers at south edge of circle, flip camera 180 degrees and do it again.
Early on, it seems like placing/dodging puddles is more difficult than the dives (which are predictable).
