One Piece calcs replacement/removal

[YmTheSuper]

So I noticed major problems with some One Piece calcs and I think they should be either replaced or removed:

Spoiler: Sanji kicks the Sabagashira

The calc is here.

So there are many problems with this calc:
1)First of all, the calc doesn't account for the hollowness of the Sabagashira despite it being consistently shown to be mostly empty on the inside
2)For some reason it's assumed to be made of steel despite it being part of the Baratie which is completely made from wood. Yes the small cannons on the inside need to be taken into account but it isn't even close to the whole thing being made of steel and it should instead be considered made of wood.
3)Manga by its nature just happens to have inconsistent sizes, but I want to point out that the size of the Sabagashira is very very inconsistent. It's portrayed many times to be around the size of a small boats. and other times to be around the size of a ship. I do believe it being around the first size to be more consistent since we see Patty driving it multiple times and his size compared to it, Krieg tossing it and Sanji kicking it and it clearly isn't as large as the calc makes it to be (Also these are the clearest images to use to directly scale it's size and the most consistent ones)

So I believe we should at least account for its hollowness (maybe around 80% would make sense) and change the material it's made of from steel to wood. Whether it should have its low-ball or high-ball size can be debated here.

Spoiler: Wyper's Bazooka's

The calcs can be found here
So in this blog there are three calcs which have problems with the size scaling of the trees (mainly the first 2 calcs)

1)These calcs use an unclear and undetailed image to scale the size of the trees, while there are many better images to scale their size (Their diameter isn't even close to being as large as they are assumed to be in the calcs)
2)In second feat we do have Luffy next to the tree which can be used to scale its size more accurately. We do also Luffy and Wyper next to other holes made by Wyper's Burn Bazooka. (Also even if we assume the size of the trees used in the calc is correct there's no proof that this tree or all trees on upper yard have the same size, using the tree where the feat happened to scale the size makes more sense)
3)As for the third feat we can use one of these panels to scale the blast's size more accurately. (All of them take place in the same location as the feat)

TLDR:The second and third feats should be size scaled directly from the panels where they happened.
The first feat can use a more accurate average tree size from the many images linked above (considering the trees are never portrayed to have a diameter of 145 meters like the calc assumes)

this calc uses calc stacking since a speed calculated in a different blog is being used to find kinetic energy so it should be completely removed

They're the same scene, so its not calc stacking.

My bad, removed it. We can just focus on the other feats then

Why are you just quoting my statement like that's a debunk. That's always been how it works. Man its literally the same feat, KT's blog just got K.E

What are you talking about? He's agreeing with you.

It didn't load for me

Okay thank you, and sorry for being hasty.

 

[Damage3245]

The OP's critques of the calcs look valid to me.

Hmph, aight

@YmTheSuper If another calc group member agrees with your analysis then you can probably go and create a CRT to address the profiles affected by this.

Actually wait no, remove my agreeal (I"m not even a cgm so my agreeal doesn't matter) for the first calc.

The Sabagashira is canonically supposed to be much bigger than the merry so that doesn't make sense. And even if it wasn't I put 2 ends there.
I compared it to a mackarel. The fish is already hollow. I just substituted its organs to steel.
The insides has large chunks of steel weaponry there

The Sabagashira is canonically supposed to be much bigger than the merry so that doesn't make sense.

Yeah, i completely understand using the scene where it's next to the Merry since it's a clear panel where it's the focus. Either way the difference between the two ends in the eye diameter isn't big (154.12 cm vs 262.18 cm) and I only gave the average as an option since that really isn't my main issue with the calc. (Although I do think this panel can be used as an end that's around the middle of the way between the other two ends since the eye would have a diameter of around 184 cm and considering that square cube law has a very fast growth rate in mass and volume compared to length I think this could be used but either way I don't really have a big issue with either end)

I compared it to a mackarel. The fish is already hollow. I just substituted its organs to steel.

The issue with this is that you have to assume that both the actual mackarel head and the Sabagashira have the same hollowness and structure and that the organs in a mackerel's head take the same percentage of volume as the weaponry inside of the Sabagashira.

When you're replacing the material that the fish is composed of into steel at the beginning of the calculation you're assuming that it's flesh, bones and organs would all be composed of steel, this is a problem all of these parts have different densities and you are changing all of them into a single density changing the percentages of the mass of each part (mass and volume of all of the parts of the fish would become proportional and it's clear that the fish head percentage of total volume is less than 22.5% especially considering that the rest of the fish isn't hollow while the head is partially hollow changing it's percentage of mass).

Even, if you want to replace the organs with the steel the weaponry is made of you would have to find the percentage of the fish's mass taken by the organs inside of the head rather than the percentage taken by the head as a whole (You can see here that the percentage of the mass taken by the organs of the fish outside of the head is around 18% and since the head has many less organs and is partially hollow then the organs in the head should take a percentage significantly lower than the 18%, The internal organs outside the head of a mackerel are larger than its entier head, minor gore warning just in case because this shows the internal organs of a fish since I don't want to get reported for posting a picture of a fish).

Also I'm pretty sure that most of the mass of a fish's head is in it's bones and jaw (Which is the wooden part of thd Sabagashira) rather than the organs and that it being compose mainly of bones is why it's takes a significant portion the mass despite that not being the case for volume.

Imo the best way is to just directly calculate the volume using the Sabagashira's shape and using panels from the manga if possible rather than using the mackerel's anatomy and composition.

I'd also like to note that the fisheye is ALWAYS depicted as being near the size of the ship's fences ( slightly smaller ), which are ALWAYS depicted as being shorter than humans. I think the best way to scale the ship is through it's own proportions, since it's proportions are most consistent. Comparing it to a whole other object assumes Oda meant them to be compared 1-1, which is unlikely given the inconsistency in it's depiction next to other objects and his track record of not drawing different objects to scale. For example, here is Oda's establishing shot of a character confirmed to be only 80 meters next to Sunny, which is confirmed to be 56 meters. I'd say it's own proportions hold more weight. The current calculation has too many issues with it.
