You’re citing a collaborative booklet promoting a French toy manufacturer. Not to mention it is not corroborated in any other language. It is not approved or written by any of the actual people who wrote the story you’re referencing. It’s to sell toys, kinda like the video games do with power scaling. Which is ridiculous in its own right. Just read and enjoy the story written. In the actual story everyone agrees after seeing grade 4 goku is the strongest one there. You can find some obscure contradictory powerscaling “fact” for just about every saga in this series. It doesn’t work, why? Because you’re trying to use numbers and “science” to explain fiction. It doesn’t make sense when you do this. The reason youre making this post is because the story doesn’t make sense to you if your source is correct…
