There is no cap

I believe that speed is controlled by an equation, based on the graph

here it is

(sorry for this math XD, its what i do best lol)

k=x*y

k is a constant, this number could be anything in the code and it never changes

x and y are ur speed, and the boost in speed, this includes artifacts AND E ability

So this means, you can go infinitely fast, but you would need a infinitely large speed boost from ur arts and E to do so.

This also means you cant be at 0 speed

Why do i think this is true?

I'd recognize that darn graph, the first one in the original post anywhere.

I am pretty sure about this, the graph tells us everything

If you want you can search it up

Also, this is my idea, i didnt steal it, its all original ideas from myself.
