I can't see the source, so I just have to ask something.

Is the speed in the article supposed to be limestone cracking speed, or the longitudinal wave velocity of sound in limestone created by drilling?

I ask because I've found values like 3,200 and 6,000 m/s.
 
Just as I thought. Those are P-Wave velocities. That's not the speed that limestone cracks at, it's the speed of sound in limestone. It's like arguing that diamond cracks at mach 35 because the speed of sound travels at mach 35 in diamond.
 
Also the calc didn't use the canon width of the cave, but the old out of date fan calc version.
 
Neither. Because neither is cracking speed, they're the speed of sound and other pressure waves created by drilling in limestone.
 
He used superhuman reactions for a regular human ( albeit a jet pilot ) doubt it gets accepted
Normal humans in opm are already superhumans(kid saitama) and by now we already know that ppl in opm who just train become superhumans (a lot of heroes, tank toppers,dk fans...etc) so a very highly trained pilot being a superhuman to a degree wouldnt be suprising really

The canon width of the cave should not be used. It's ridiculous, Brave Giant travelled at least 27 floors by my count before it reached the cavern, and in the very same panel where Brave Giant says that, I count 23 floors between Brave Giant and the water's surface. Are those floors each really about 2 meters on average??

I dont see why they couldn't be in some cases. The entire underground base heavily varies in room sizes. It also was a rewrite ONE more or less forced Murata to do since that was like the 4th version of that encounter. If he didn't want the dialogue in there he wouldn't have included it.

Was gonna make that point, OPM canon sizes are quite wack.
 
If we use the Brave Giant positioning, it's about 3.5 metres per larger storey if we go half-way through the ceiling and half-way through the floor. The actual spaces in between is something like 2.2-2.6 metres, while the smaller ones are around 1 metre.

Even so, that's very small. The stories in my house are 3 meters from floor to ceiling, and they would struggle to fit the likes of Bug God. 3.5 meters might fit the larger members of the Monster Association, but there's no way Brave Giant could fit in a space of that size, or Overgrown Rover, Great Food Tub, G-5, etc. Those guys are all 5-10 meters tall, so I would think the larger floors would be something like 10 meters to fit larger members and the smaller ones more like 3 meters, enough to comfortably fit creatures about as large as humans.

But there is the second, where is the shear.
 
I agree, just mentioning the size in the panel you gave.
Fair enough. I just wish ONE (or Murata or whoever is making these numbers) would stay away from math. About half the time the canon sizes don't line up well with the manga appearances at all. Or even better, they can hire me to pixel scale every character in every single panel they appear in and I will make the canon sizes for them, hehe

It's probably Murata's fault. ONE is the one who does the majority of the dialogue and plotting while Murata does art and a decent chunk of thr character designs. Murata goes for big flashy stuff which doesn't fit with ONE'S ideas.

But ONE is the main guy so if there's an art vs dialogue inconsistency we should probably take the dialogue over the visuals.

Do it
 
How are you proposing the calc should be altered?
I have an interesting idea. What if instead of counting the number of stones on the GENERAL background (2711), we just find the average number of stones in 100 cubic meters of space? We will take the mass of the largest stones and add to the mass of the lightest and tallest stones and so find the average mass, and then multiply their number in 100 cubic meters of space by the volume of space in which they are located?

Here and here we see their number in space. It's just that 2711 is too little. At an altitude of 100 or a little more meters in a radius of hundreds of meters, there ALREADY more than 100 stones, and we have a huge scale. 2711 is too unrealistic. Otherwise, it would mean that one stone is in every 700 meters of cubic space (According to rough calculations)

Yeah, we could do that but I don't know how that'll affect the calc. I say you can use the page right after the stomp as it is easier to see and count the stones that were sent flying. From that we can find rocks of three diff. sizes: Large, Medium and Small and then after finding the mass of one such rock, we can multiply it by the number of rocks in each category.

The distance they were launched remains the same though.
