Barring the arguments from the OP for a second, I would still agree to adjust, if not remove the multiplier because the main justification comes from
this blog from
this CRT which have a few problems in my book.
First off, why would "keta chigai" here mean "order of magnitude" at its most accurate level, especially when the blog literally concedes that certain translations that
wouldn't mean a 10x amp would be valid in the first place? Keta Chigai has numerous meanings (in a different league, unbelievable, incomparable, unimaginable)
which would all fit the intent of the databook without forcing a 10x jump in overall statistics and as such, the blog would assume it would mean the numerical amp without actually explaining why. Thus, the claim that "keta chigai would be the most accurate to mean order of magnitude" was never actually proven here.
Also, claiming the databook doesn't explicitly state which order of magnitude it meant would be claiming it said "order of magnitude" in the first place and not something like "extraordinary fighting abilities" like the official translation used; again, the blog never proved that the former was the case, just claimed "it's the most accurate" without backing for it. It's more likely that the reason it didn't specify which order of magnitude it was is because
there is likely no order of magnitude to be stated in the first place. The statement can be equally interpretted to mean something that grants it an unquantifiable amp with this line of reasoning alone and claiming it to be a 10x needs to be further justified.
Not only is this just blatant whataboutism due to the contexts being different (since the narratives are different), just because Keta Chigai was used for those verses and was accepted, that doesn't mean they are immune to scrutiny and honestly, if the same line of reasoning was used for these verses, their examples should get nuked as well. Just because one verse does something with a certain kanji, that doesn't mean another verse using the same kanji is valid; two wrongs don't make a right.
None of these examples actually deduce that the 10x amp is the one that
has to be the case, all of these examples can be equally valid for an unquantifiable amp.
In short, I agree with the premise of the thread, but it's unrelated to OPs arguments for it.
