There should be a block called mouse speed that tells how fast you move the mouse.

I beleve there is a way to identicate the speed of the mouse poitner. I have seen some people manage it. I have no idea how.

You could record the position of the mouse pointer, wait 0.02 seconds, and measure the distance between where it was and where it is. Depending on how often you computer updates the mouse position, you may have to wait a bit longer, but probably never more than 0.1 seconds.
