Reletive prices

[Pi]

I have a question on a structure of the app and thought that this would be the place to ask. When a list of cards is arranged by price in the database, how does it decide which card is more expensive? I try to use the median price for general reference, and am finding that when I try to list cards in descending order and find that the m. price is not perfectly descending, but it kind of fluctuates flowing downward. In short, how are the values of prices compared relative to other prices?

It uses median. Database is shipped with prices set to zero, so you first need to download them all using Offline Cache.
