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 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.
