Just read the passage - it is obviously flowery language. The same thing can be said for the Longinus having infinite mass - unless you really think that Reinhard's lifting strength is infinite.
We have no feats for Reinhard because he doesn't do anything but stomp the cast and then become a god. And you know full well that is a massive false equivalency.
Masada is the author of both Senshinkan and Shinza Banshou and knows how strong he wrote his own characters - if he states Reinhard is comparable, and nothing contradicts it, then the statement should be usable.
You do know our Senshinkan profiles were written by someone who actually has read the verse and knows the cosmology, right? The Senshinkan gods aren't 1-A because nothing in the series proved that it was - if 1-A Senshinkan was a thing, then it would be apart of our profiles.
And no, comparing Atziluth Reinhard to Amakasu's Gods is not more logical just because they are both Gods.
Methuselah is a "God" - does that mean he is 1-A too? No, it doesn't. Your logic is faulty - just because both verses have gods doesn't mean that Masada was comparing each verses gods.
No, it isn't inconsistent.
And I am 99% sure that Yetzirah Machina never cracked Trifa - AFAIK, it was one hit in his Briah that cracked Trifa's shell and another would have killed Trifa. Even if it did happen, it doesn't matter because it would clearly be an outlier.
Not to mention, that even if Reinhard was downgraded to 4-A like you are suggesting, then that still means that Yetzirah Machina cracking Trifa is a massive ******* outlier, unless you think Ren and Tubal Cain have 4-A durability.
Dude, that higher dimension thing is a joke - its just flowery language.
Seriously, stop being Amelia Bedelia and learn what a metaphor is, please.
