When I saw that formula  it was obvious to me that it does not weight the 
data. Since I found that strange I searched for the documentation. And it 
says: "We are aware that the current formula does not actually weight the 
data aggregated for rankings (the formula was misdesigned and has not yet 
been replaced)."
