The Rank calculation used is this page is taken from Freshmeat, for an explanation see here
weighted rank (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C
R = average for the trig (mean) = (average score)
v = number of votes for the trig = (visits)
m = minimum votes required to be listed in the top 10(currently 1)
C = the mean vote across the whole report (currently 5.507735089597)
