How do we calculate perceiving people as completely immobile while moving around? How would it work in this feat?

So i, yet again, bring this chapter

GOSU - Ep. 12 - The rosy-cheeked sword devil So Hong (2)

When his master dies, Gang Yong pledges to avenge his teacher at all costs. After training his martial arts skills in seclusion, Gang Yong sets off to hunt down the traitors and make them pay! But when he gets to town, he discovers they're... already dead? Well, what's he supposed to do now?!

I gave it another look and i realized something. Last time when i brought it up i was wrong as i though the water moved while the two were moving around.
Now that i look at it closer, the panels where the water moved after they had the encounter are happening in real time and are both the same color while when the encounter happened the author used a black background to signify lack of movement. With the context, its clear that the two moved so fast that nobody and nothing could have moved an inch.

Them communicating can be explained either by the classic "talking despite moving faster than sound" cliche that is seen in basically every action or potentially telepathy as the main character at one point uses some form of telepathic communication with another fighter in later chapters.

Now the question is, how do i calculate this?
They were moving so fast the everything seemed to be frozen in time. I remember seeing some blogs that addressed this but idk where they are.

How do i deal with this? Please help.

Ah yeah, that's what I said the first time.

Anyways, from the calcs I've seen, you just take the speed of a thing and divide it by 0.001, for this example, the water falling could probably work.

thing is i found this

and now i am confused

 

[Rikimarox2]

Now I'm confused with you as well.

i deadass don't understand how to use that method

imma just call up dt

Current standards are this, although the 1px thing likely gets revised to "thickness of a line" or something to be independent of resolution.

However, from a look at the feat the water definitely moved while the feat was happening. So what you want to do is figure out how far the water moved, get a reasonable estimation for how far it was moving (maybe using falling speed) and get a timeframe by dividing the moved distance through that speed.
Then just measure how far the warrior moved during that period and divide it through the timeframe to get speed.

I suggested that initially. The distance moved by the warrior is easy enough.

It's the free-fall stuff and the mass of the falling water that concerns me, since the water is all over the place and not one solid block.

I disagree. If you look closer the background turns black when they are moving and right around the moment the water moves we can see the black background disappears and the light blue background comes in signifying movement. This is proven by the fact that in the images with the blue background have movement happening in them.
This means that the artist used a black background to symbolize the lack of movement and when the blue background comes in like a wave iske when they stop moving at high speeds and thus the water actually moves. It only moves when the blue background is there.

I think I’ve seen one calculation that got accepted where they took a frame of the movie playing to get their speed which can be found here

Well there are no frames in this case sadly, but I'll try the line thickness method.
Last time I tried to calc it the line was around a pixel either way so just need to get a few things adjusted and get some calcing done
