My guild is at bracket 204. What is the minimum amount of brackets we will climb when we win our bracket? What would be the minimum for second place in a bracket?

Do our points have an effect on how many brackets we climb or is it only about winning?

If points have an effect, is it about relative amount of points or do we have to hit some specific point range in order to maximize the amount we climb?

Knowing these things would help us determine whether we should require participation from all guild members or not. Thanks in advance for all information about the subject.
