Just posted this in another thread. That may answer your question.

I did a quick calculation and a win rate of 3PTBB/100 means that there is 99% chance than Kane's true win rate is between .8 and 5.2 assuming a standard deviation of 38.27 (mine). Of course there are many factors that stats neglect like the fact that sometimes games are far easier, for example when it is first spread on a site.

Those numbers show that it is difficult to prove that someone is supposed to win at a given limit.
