The formula is

with the variables p := (f_i)/n ; n := n (arbitrary, but just to be clear here) and a := level of significance.
Notable is also z[s_] := table of the Gaußian distribution to a chance of s .

Beautiful! That's EXACTLY what I was looking for.
Basically I'm thinking that any check/counter ranking system should operate on an "CRE"-like principle, where the measure compared is value minus n-sigma deviation.
