that's well calculated but remember just half of kurama is stronger than the other 7 tailed beasts combined
Well, at least equivalent to 5 combined. Shukaku and Songoku weren't present. But that would still mean that 50% Kurama has 50.9% of Shinju's chakra, based on Bangimaki's results.
Guh, the math doesn't add up because the chakra distribution of the Bijuus don't make sense. Kurama in the equation completely destroys any reasonable calculations. 100% Kurama will have almost all of Shinju's chakra and the rest have almost nothing. Yet, that's not the case, given how powerful each of them are in various comparisons.
Although Gyuuki is allegedly the second strongest under Kurama, he seemed semi equivalent to the other 7; none overtly stood out between one another and were all similarly sized (100% Kurama is twice the size of them), which gives the appearance of them being similarly powerful. All of the Bijuus also have a reputation for being living masses of chakra far surpassing human capacities, and possessing of strength and durability that make them more akin to walking natural disasters. They were coveted over to be living weapons, and a Jinchuuriki is almost automatically Kage-level. Yet, as the series went, on, the Bijuus themselves each have wildly fluctuating power in each of their appearances and have not lived up to their hype, only coming across as Kage-level themselves despite their village-busting Bijuudamas.
In a literary sense, 50% Kurama should never have existed and has had no actual impact on the story, in that case Bangmaki's tallies would be more accurate. Although, if I had it my way, all of the Bijuus would be much closer in power with Kurama inching out the others.
