I know, but because we know that it is only countably infinitely bigger than the human world at best (really, I'd say that the manga scan implies that they're comparably large), it cannot be of a significant 5-D size.
I see. Well, the current (and soon to be) standard page doesn't mention the 5D space needs some uncountably infinite statement or something similar (unless the argument in question was about being infinitely bigger than tier 2 which it isn't), I understand where you are coming from but if I'm being honest this just sounds like unnecessary nitpicking for the sake of it as the threads DT participated didn't have those very specific statements or implications unless it was for a different line of reasoning altogether.
In fact, current standards only mentions this:
"A: One of the more straightforward ways to qualify for Tier 2 and up through higher dimensions is by affecting whole higher-dimensional universes which can embed the whole of lower-dimensional ones within themselves. For example: A cosmology where the entirety of our 3-dimensional universe is in fact a subset of a much greater 4-dimensional space, or generalizations of this same scenario to higher numbers of dimensions; i.e A cosmology where the four-dimensional spacetime continuum is just the infinitesimal surface of a 5-dimensional object, and etc."
Also the manga is imo pretty clear, it mentions how the human world is a ray/line/streak of light in endless/infinite darkness (aka the demon world) establishing a pretty solid comparison while also giving us the size of the demon world and also satisfying the standard quoted above.
Asking for more than that and we would be running in what the FAQ page describes here:
"In that regard it is important to consider that, by its nature, it is not possible to accurately depict 5 dimensional space. As such depictions of the multiverse are usually not to be understood as accurate representation of the distance between the universes, but rather just qualitative analogies of the multiverse's structure."
Even now I can point out
some threads where staff members ask for examples of verses that actually have the kind of thing you are asking (uncountably infinity stuff) because none can pull that stuff and I remember a thread where even DT said he doesn't know of any verse that deals with such things.
Basically it's pretty much impossible to get that kind of comparisons or statements and so the standards don't require them unless someone is gunning for "infinitely bigger than x" arguments.
It's like, you don't need a statement of being uncountably infinitely bigger, but if other evidence confirms that you're less than uncountably infinitely bigger, you cannot be bumped up a tier.
I mean, the standard doesn't mention anything like that and the threads I used as reference don't dwell on that either, in some cases size isn't even established for the 5D space afaik, just that is has relevant magnitude (like the GoW threads).
Your reasoning seems to be as follows, correct me where I'm wrong:
P1. An infinite amount of L2-C realms is a 2-A multiverse.
P2. DT said that a 2-A multiverse is displaced across a 5-D axis.
P3. DMC has an infinite amount of L2-C realms.
P4. The Demon World is said to be the superset/container of these realms
C1. The Demon World is the 5-D axis/5-D container of the realms
P5. The Demon World is infinite in size
C2. The 5-D axis is infinite in size.
The error is that the Demon World being a 2-A multiverse does not mean that it is -- itself -- the 5-D axis. If it's the 5-D container of those realms, it would still be the case that none of the information given tells us that the 5-D axis is infinite in size, because it would still be accurate to call the Demon World "infinite" by virtue of the 4-D infinity within it even if the 5-D axis is arbitrarily small. You cannot infer that the Demon World is the 5-D axis by virtue of it being described as the container of these L2-C realms, that's not how we treat multiverses in terms of being containers of many universes. A multiverse containing infinite universes and also itself being called "infinite" does not mean the 5-D axis is infinite in size.
Here are the pertinent sections of the FAQ that make this clear:
From what I see is that you are trying to apply the wrong standards (Q: Is destroying multiple infinite multiverses a better feat than destroying a single one?) to the feat in question. To expand on this, you are claiming that destroying multiple 2A structures is the same so the Demon World should not qualify when in actuality the feat in question is the Demon World acting as the higher dimensional space that holds several 4D constructs without interacting with each other like how a 5D space does.
However you are correct when pointing that "X being a subset of another set Y does not imply that Y > X in terms of size". If you recall my first post I linked DT's comment regarding this.
Basically "X being a subset of another set Y does not imply that Y > X in terms of size" is what DT was talking when he mentioned
how the tiering system works regarding tier 2:
"Space being infinite in itself doesn't matter, as space at that level is infinite in some sense anyway. You would need to be told that either specifically its 5 dimensional volume is infinite
or that specifically the 5th dimensional axis (the one you add to the standard timelines) is infinite (or very large) for that to work. But I figure if you have information that specific then you wouldn't need this thread.
In general, infinite could mean infinite by 3D or 4D standards, or in the sense of countably infinite times larger than a spacetime continuum, so that is just not enough."
If you recall I summarized his post like this:
"How does a multiverse work? Well it's a bunch of 4-D constructs (your standard Low 2-C universes a.k.a. timelines) displaced across a 5-D axis. The difference between Low 2-C/2-B/2-A and Low 1-C is that this 5-D plane is on insignificant size in tier 2 while it is of significant size in tier 1."
In this case, like I said before, the demon world acts as the 5th dimensional axis that exist between the standard timelines inside of it and since it is stated to be infinite then fulfills the criteria set by DT. Moreover the
FAQ supports this line of thinking:
A: One of the more straightforward ways to qualify for Tier 2 and up through higher dimensions is by affecting whole higher-dimensional universes which can embed the whole of lower-dimensional ones within themselves. For example: A cosmology where the entirety of our 3-dimensional universe is in fact a subset of a much greater 4-dimensional space, or generalizations of this same scenario to higher numbers of dimensions; i.e
A cosmology where the four-dimensional spacetime continuum is just the infinitesimal surface of a 5-dimensional object, and etc.
