Why do people belive that adding 2 sku's would nearly double the highest selling one? It makes no sense. Ranks are always scalable going much higher the higher the rank. So a #30 is much higher than a #50 and #50 higer than a #64. So the combine sku's wont be past #40.

Actually we have no idea on this.. so really adding together listings is futile..    

Lets say a #30 spot means it sold 50 that hour.. and the #50 could mean it sold 40.. we have no idea of the difference between rankings.. it could be 1 unit each..  who knows..    #10 spot could be 80 units.. so the combinations of #30 and #50 could be 90 units and put it above top 10.. but again.. we have NO clue.. it could be the complete opposite and mean nothing..  

It really could go either way.     

Your right, it could go either way, but seing as how this is based on millions of consumers across the country, the rankings are also a singh of popularity of the item. Its an statistical imposibility for it to be that favorable and much closer to a negative outcome considering its such a large sample size and wide area.
