I have been observing for a while now that there seems to be no real rationalle for the ordering of problems when you sort by frequency for a given company.

For example, if you click on the Amazon tagged questions over the last 6 months and sort by frequency you will see that Basic Calculator III shows up at about number 75 having been asked 8 times in the last 6 months. However, Add Two Numbers shows up 9 questions after basic-calculator-III in the list even though it is being reported as being asked 41 times in the last 6 months.

Moreover, if you add up all the times Basic calculator has been asked total by all companies in the last 6 months you get 32 but Add Two Numbers has been asked 161 times.

So no matter how you slice it it doesn't make any sense.

Additionally, you will find many questions in the "Top Amazon Questions" list which have been asked way less than 41 times by amazon.

There just doesn't appear to be any rhyme or reason to the way that the lists and frequencies are done.

Can anyone please explain it to me? Or point me to some sort of documentation that explains it?
