Also, another thing about Geo’s thread is, I don’t think DontTalk disagrees that an overarching timeline is Low 1-C as long as the lesser timelines are serviced by their own time dimensions. He clearly read the OP, and responded that “the last thread wasn’t meant to change the standards,” so it’s not like he hasn’t seen the current phrasing for that section of the faq. He said multiple times that a time dimension spanning timelines shouldn’t qualify in itself, nothing about spanning time dimensions. I think he’s on the same page as us in that a higher time dimension is orthogonal and inherently a different direction.
I believe that so far, he’s mainly addressing ways to demonstrate higher time dimensions without confirmation of lesser timelines having their own time dimensions: whether it be explaining how different universes having certain flows of time would be indicative of existing under parallel time dimensions (e.g. if time flowing backwards in one universe means something), or how an overarching timeline could be interpreted as having 4-D snapshots and measuring the continuous change of the multiverse (which Dragon Ball has anyways).
