To dissuade someone from doing something is to try to get them to stop. You seem to have the impression that it means the same as persuade? I don't really know what to say to that, seems like a misunderstanding.
"too fast, or I’m slower and even one push would put me in a speed faster than required to skate the spot." This is what I am referring to. If you are going too fast with one push, there are other ways of getting speed. If they had actually provided some example of what they think you need less than a single push of speed to do, it could actually be discussed more in-depth. But for now, and as I said in the original comment, there are multiple ways to choose your speed already in the game, I'm of the belief that it's possible they maybe aren't aware of all of these.
