I have DB access to the back-end, which I’ve been using for some of my articles. I can use it to gather a lot of data quite quickly, though making some nice graphs and summaries out of it takes time (though likely much less than doing it manually).

I was thinking of trying to make a selection of the last 6 months before rotation and next 6 months on a per set basis and then averaging the prices (or maybe averaging the price changes?) for every card that starts higher than a given value at best buylist (I’m thinking $1, but maybe that selects too many). The big advantage of having the query is being able to run it again at any time (and because I query from a spreadsheet program I can also couple that to the graphs, so those can then also be generated automatically).

This wouldn’t be a particularly easy query to write, but I think it’s doable with some research on rotation dates.

Please do. Having access to more data would open up a lot of possible analysis. Gathering the data that I did was somewhat tedious and time consuming…automating it would be amazing.
