The distance between a spoke and a triangle is the minimum distance the meteors should be placed apart.
If you're just here to complain about getting one-shotted for failing a mechanic, how about these:
Judgement Bolt
Hellfire
Atomic Ray
Earthen Fury
Heavensfall
Aerial Blast
Viscous Aetheroplasm
Tidal Wave
Diamond Dust
Lunar Cry
Memento Moogle
(these may or may not still one-shot you if unsynced, I haven't tried any of them)
