Like I said, it all hinges on that one calc. Based on what they presented, it seems a bit absurd, but again I'm holding out judgment until they release it fully. In fact, here's a quick summary of what they said on the q&a.
-Why do the verdicts now just come down to who make sthe bigger explosion?
The numbers do seem to be the focus, but they do adress the other points of the arguments (eg Hiei's counters to Sasuke's abilities). They still do focus on the logic of the fight like they did in season 1 and 2, just now with the numbers too.
-Why did use an anime-only filler feat for Hiei?
A lot of people watch Death Battle. They can't go full composite, but people would question why they're using nothing from the movie or anime they watched. They create a broader version of the character, they see different timelines as the same character in a different story. Hiei's planet-level stuff originates fromthe manga where it's an important plot-point, the anime just allows us to see it and supports the main timeline
-Why didn't you use the data book statements for Kurama and the like being planetary?
They don't take statements at face-value, like word of god. They used it for Hiei as the planet-level stuff is supported by the story, see Genkai having to watch Yusuke's power level. They have context, and the Naruto statements are likely not literal
-You didn't mention _______ for Sasuke, he could have won with that
They don't have time to cover everything long-running characters have in 20 minutes. They skip things that aren't super important, but they still factor them in
-Why did you just use Madara-arc for Sasuke and not Boruto?
They didn't. They just used him for the animation because he's more recognisable and that's the sprite they found.
-Why did you say the Jagan could counter the Eternal Mangekyo Sharingan when it's more powerful?
It's hard to scale mind hax and illusions in a linear way. They just base it off their overall powers. The Jagan is clearly increasing with Hiei's own power or it's always been super powerful. Even as an upper s-class demon the Jagan still works and is useful. It's not 1-1, but it's the best they can do with immeasurable stuff like this. Same for the Amaterasu.
-Shouldn't Kaguya be universal as her attack was going to destroy her entire dimension with stars in it?
They recognise it's hotly-debated. There's a long segment talking about it, but tldr they think it's more likely she was just destroying the planet, but either way it's not really relevant as Sasuke doesn't scale to it at all.
-Why did you scale Hiei to Yoko Kurama's max speed when power-levels don't work that way?
They know, they said thisback in GVS 1. Power-levels are hyper broad generalisation of characters, so they aren't 1-1 scalable. They just used this because Hiei is clearly faster, we just don't get to see it as he lowers in prominence later in the series. It's just them estimating the bare minimum speed he could be using power-levels, there's no other option.
-That Yusuke/Yomi cloud calc seems suspicious, can you elaborate on it?
They recognise that going over the whole calc in the episode or in the cats woudl take way too long. Ben says the research team, especially Strunt, took a long time to make it and analysed it from every possible angle. He says he'll post the full-calc on the community and link to it on his twitter.
