After getting the answer of this question, I am confused. It says:
n% is percentage of users having reputation change this X.
Its alright, but how does this no. get smaller for top rankers? If it has to do with user base below it too..
n% should be higher with simple maths.
I want to know exact formula system uses to calculate it. My concern is
top n%, not
this X. I know,
this X is chosen based on best performance among all X.
