Is there a way to define what is still say, chordjack speed and then what becomes pure vibro, as in, what bpm is the cap of chordjack, and what bpm is the lowest form of vibro? including longjacks triples, hands, jumps, etc.
Vibro doesn't really have a speed cap, it's more of a term for the technique. However, vibro maps are typically found in insanely fast speeds such as 350+ bpm, though there are ones lower as well.
180 Chordjacks are pretty much vibro 180 bpm jacks are just speedjacks... looking at sujak's videos 60-70 kps (without double setup) in other words 200-230 bpm vibro is the max in 4k at least
