I already explained literally almost everything here, let me answer the bold part though.
How would an army be overtime output? The point they're making is that Yaga has the potential to be special grade cause he would have a full army of autonomous, self-sustained cursed dolls. It'd be like he's a country of his own with his own army (do you get it now). Just like Geto with his curses could overthrow a whole country via also having his own army of cursed spirits. Yaga's army with their combined output would beat any grade 1 sorcerer in output easily lol. And the mai example that you gave is the same thing that Mechamaru does, even if she somehow did that, it would be a temporary output that would run out after one use in this case. This wouldn't grant her special grade because it would be a one time thing that she can't reguarly do, while Yaga can just keep creating dolls non stop.
See you’re getting there, Yaga would quality as a SG because per Kenjaku’s own words, to be a SG you’d need to be able to overthrow a country. That’s it.
“Yaga's army with their
combined output would beat any grade 1 sorcerer in output easily lol.” Why are you bringing this up? This is completely irrelevant to the title and is only being used to try to justify your interpretation.
The output generated by him creating the army isn’t what’s being assessed when giving his title, it isn’t referenced, depicted or implied anywhere. It’s entirely irrelevant to the assessment. His capability of creating that army is what puts him in that discussion.
My Mai example is a perfect deconstruction of your argument my guy.
You’re claiming that the total output of him creating his army is part of the assessment of special grade. If this was true, literally anyone would be special grade because they could indefinitely output energy overtime.
I just used Mai because she’s a bum, but it would apply to literally anyone you can think of.
The amount of output generated due to him creating the army isn’t considered in the assessment, it’s the fact that he can create an army is what’s being considered.
“while Yaga can just keep creating dolls non stop.”
Uhhhh what???? We literally know nothing about how much energy it takes to make a doll, or if he can consistently make them back to back no problem.
This wasn’t even brought up in why he was recommended to be a special grade.
It’s literally the fact that he has the potential to make an army of dolls that puts him in the discussion of special grade.
It’s not the amount of output that total army would have if you add it all together, it’s not how long it’d take. It’s literally the fact that he has the potential to create an army.
Keep in mind that even Gakuganji, a Jujutsu Tech higher up had no idea that Yaga needed 3 cores to create panda and thought he just replicated soul information from physical information.
Your point…?
You do need a level of output to be a special grade, otherwise Kenjaku would NOT say that. Unless you think he's talking about special grade spirits output here, which if you want to, you would need to say that grade 1s scale to two year charge. (Also why did maki catch a stray?

)
You dont my guy

. Read what Kenjaku is saying.
To be SG you’d need the capability to overtake a country, he says Yuki must have a high output extension of her technique that’d allow her to be a special grade, because the strength of her punches and that simply being all their is to her technique shouldn’t be enough to qualify as a special grade, because he doesn’t believe that’s enough to take over a country.
The reason he says she must have a high output extension of her technique is due to the nature of her cursed technique, it’s applying hella mass to her arm which is allowing her to punch hard, so if she’s special grade she must have some extension that’d allow her to output enough energy overthrow a country.
Get what I’m saying? Due to the nature of her CT, her being special grade means she has a high output ability that could allow her to fight off an entire nation. This does not mean special grade has a set level of output, it means you can become a special grade due to a high output attack.
Geto and Yaga can be considered special grade because they can create a super powered army to take on a nation, thus fitting the requirements.
Yuki can be considered a special grade because she has an attack with enough output to literally destroy a country, or to be more specific, the entire world.
This is what Kenjaku was concerned about, “if all there is to her ability is punching hard, she must have an extra ability that allows her to punch VERY HARD, at least to the degree to overthrow a nation”
I never said they used ultimate uzumaki as his way of being a special grade, I said his curse manipulation is what got him the special grade title since it allows him to overthrow a country with thousands of curses.
So why is there confusion????
Because... they are special grades and that's literally their strongest attack? What is this question lol
They are special grades because of their army my guy, not because of their giant beam attacks.
As per your own comment, they aren’t considered special grade because of the output of those beam attacks, so how can you say those attacks should higher than social grade level? Do you not see the redundancy in that claim??
When did Kenjaku say yuki's base attacks can one shot him what, Kenjaku was only afraid of her extension, which turned out to be the blackhole, that, yea, would one shot Kenjaku, how does this matter?
Her normal output attack literally ripped off two of his arms. If that would have hit his face you tell me what would have happened.
