Seriously I don't really find this enough for 1A/1A+ even there are Second hierarchy, at least mathematically. Assuming we consider layer A to be the first/lowest layer higher than baseline, layer A would be L1A (2^Aleph 0 or "R" spatial dimensions) then the whole hierarchy with its infinite layers is just R*omega spatial dimensions are so so much smaller than 1A requiring R^R (Aleph-2/2^R) spatial dimensions. In other words 1A would be equivalent to UI^UI spatial dimensions, with the difference between each spatial dimension and the previous being UI times (UI = uncountably infinite/Aleph-1/2^Aleph-0, omega = smallest countably infinite ordinal/"set/number"), whole hierarchy is this case only UI*omega time (much,much smaller than UI^2. Even this requiring aleph-1 layers)
I know we always treated the second hierarchical cases like 1A+ but they are like circumvention and don't look closely at the true scale of the infinities/aleph, even the explanation page clearly states the difference between each aleph far beyond than entirely hierarchy below, in other words the difference between aleph-2 and Aleph-3 is much larger for aleph-2 and aleph-1, generalizable to any higher aleph/step in 1A. Literally, transcend baseline 1A character like they transcend 11-C (or far superior than that) isn't enough to just one "step" of 1A, even between two Aleph (Aleph-3/baseline 1A and Aleph-4) has uncountably infinite "steps/levels", whether it's Aleph-2 or 1 number of "steps". For simply, even jump from baseline Low-1A to baseline 1A, still need not just second infinite Hierarchy (difference between each level is baseline L1A and 11-C) but literally uncountably infinite number of infinite hierarchies with each superior to last as a whole, treat all their levels equally (not add layers like dimensions or "omega+1/2/3.., epsilon, velben,..."th level, these only in one hierarchy) and difference between two "steps" in 1A equal if not far superior than this, let alone "Alephs" to 1A+ upward
Personally, I feel the majority of characters from Low-1A and up reach those tiers without even showing such feats/hierarchies, only cherry picking philosophical metaphysical, transdual elements, treating them like large cardinals, for me it's the worst NLF thing that doesn't have to be treated like a joke or wank by the majority. I only see Unsong, SCP and Downstreamers legit for their tiers if we go "My infinities bigger than your" (Unsong"s 0 is bad but at least their H1A still make sense in some way although so vague and could be just 1A+), the rest is just worst, I don't see how they could be 1A+ let alone H1A and 0". Also Marvel is literally worst ever exist because their transfinite statement is just Low-1C to H1B at very best but still qualified for L1A upward. Literally, there is CRT trying to upgrade Marvel to H1A, all scan related to infinities/transfinite only give 2A according to most people
