Naruto: Part 1 calc problems and replacements

So I noticed some issues with some part 1 Naruto calculations.

Current calculation

The main problem of this calc is that it uses the vaporization value of rocks when the material that was destroyed was clearly soil.

Other than that it is debatable whether the full volume of the crater was vaporized or pulverized considering we do see material being ejected away from the crater when the fireball makes contact with the ground with some dust clouds appearing around it afterwards.

Current calculation

So the current method to find the energy is by finding the size of the bear, using the top speed of a kodiak bear and upscaling it to the size of the large bear and then calculating the kinetic energy of the bear at max speed.

So there are three main problems with this method:
1) Our Large Size Calculations page states that:
And this isn't demonstrated (not even in the anime) so we can't use size to upscale speed.
2) There's no reason to assume that the bear's durability would scale to the kinetic energy of it moving at its top speed. We already have an example for real life Bears where their profile has a higher rating for charging at full speed compared to other stats like durability, another example is that a human hitting a wall at full speed would be heavily injured. So assuming that durability should scale to the kinetic energy of someones top speed is absolutely not a default assumption.
3) The bear wasn't moving at its top speed, all it did was lunge forward to attack Karin. So we can't scale Sasuke intercepting and attacking the bear to the kinetic energy of it moving at top speed.

In my opinion the best way to replace this is by calculating the potential energy of the bear, rather than its kinetic energy.

Current calculation

The main issue with this calc is that it scales the size of Choji's fingers to a tree by assuming the tree is the as wide as the average tree, with that width being 2.54m. This doesn't work because Jirobo's height appears larger than the tree's width on the panel in pixels despite being much further in the back compared to the tree (around two times bigger actually) and with Jirobo having a canonical height of 1.813 m which means that the tree seen here should be significantly smaller than Jirobo's height since it's in the foreground while he's in the background, so the current 2.54m doesn't work.

Another thing is using a stated character height in general should be better and more accurate than assuming a size for an object based on averages, with that object being a tree which vary wildly in size. Also additionally using the dimensions of the symbol on Choji's clothes from Jirobo's height should be better than using the fingers to scale how high Choji was launched since it's directly below the line of measurement while the fingers are farther away in the back.

I agree with the general downgrades but some of your reasons are flawed.
Other than that it is debatable whether the full volume of the crater was vaporized or pulverized considering we do see material being ejected away from the crater when the fireball makes contact with the ground with some dust clouds appearing around it afterwards.
Nope. Not debatable at all, what we see it the soil deforming, nothing was “launched”, we don’t even see the “debris” after that, they were not drawn in the state of being launched.

I also disagree with our soul vaporization value but this is for another thread.
There's no reason to assume that the bear's durability would scale to the kinetic energy of it moving at its top speed.

Yeah, it only works for IRL profiles here. For fictional ones we treat the KE for both AP and durability as valid, which is why we see a lot of profile with “Scales to his/her own durability”. The validity of this can be discussed somewhere else, but as it stands, it’s a “standard”.

As for the third feat, I don’t think yours is any better, using such irrelevant details like the nail or the outline of his shirt to me is the same thing.

Oh lol I had noticed the same problem

I overall agree with the OP, tho using the circle outline on a shirt design as a frame of reference for the Choji calc feels iffy. Is there no better reference to use?

There's also the fact that girth is a measure of circumference, not diameter. A tree with a girth of 2.54 meters would have a radius of 0.404 meters. that makes the tree being smaller than Jirobo a non-issue, but it also means that Wrath needs to update his calc.

In the same chapter, we see Kakashi use Groundhog Decapitation to grab at Sasuke's legs, and the debris surrounding where his hands emerge from aren't consistent at all with regular soil. Soil doesn't have the structural rigidity needed to fracture into large chunks or even create that kind of impact implied by the onomatopoeia used in the panel being "CHRNK!".

If you want to really be conservative with what material is used, then dry packed earth, but even that wouldn't be consistent with what's shown.
 
There is also the fact that the real value for soil vaporization is 24700 j/cc so the calc wouldn’t be changed that much anyway, but still gotta be corrected.
 
Why even make this thread without getting the calcs evaluated first
 
I was joking with my friend the other day about the City Block scale, heavily support Sasuke's fireball getting put down to Building Level but have no interest in the other two.
