How fast do you become when you move faster than human eye?

[Sekkonds.]

If Character [A] was moving too fast that humans can't even see it moving

How fast does this make it?

This source says it's around mach 51..is it accepted here?

Well, from my limited knowlege this depends on the distance you have between the eye and the character.

A human eye can clearly see up to 20fps.

In other words: Move past the field of vision in under 1/20sec.

Edit:I am also talking about actually seeing/recognizing sth., rather than being like "there was something, but I am not sure about what it was..."

If we are talking about just realizing that sth is there, we are talking about up to 1000(!)fps or 1/1000sec.

 

[Sekkonds.]

Then it's incalculable unless we have a distance?no low-End or something?

Whats the feat?

I also edited what I said, incase u didnt see

 

[Sekkonds.]

It's not a feat actually just a technique stated to move faster than what human eye can see in The Data Book

I saw it now,

 

[RatherClueless]

Well, what distance is that technique usually used at? What range does it have?

 

[Andytrenom]

Such a thing would normally be accepted as subsonic

Tens of meters..strong users can use it to move 22km with one step

Such a thing would normally be accepted as subsonic

I thought it would be impressive.

Anyway,thanks for help guys

they are capable of closing a distance of 22km without there opponents seeing them?

Well, like I said, at anything slower than 1/20sec you'd see them just fine.

Not seeing them at all, even at the last instant would be 1/1000sec (or even less).

It could be argued (for the 22km at least) that the person is too small untill they get into a 500m-1km range anyways.

so lets go with 100m and the lowest time possible: 100m*/1/20s=2000m/s

Thats the very lowest you'd get for 100m, the highest would be up to 100.000m/s

 

[Sekkonds.]

The technique itself is just a one step that happens too fast

It's stated that It's faster than what human eye can see

I think 1/1000sec should work
