There's always a comment like this I find. Some extra layer of data people want to see that explains the first layer, and it never ends - the data on data. Sometimes we just want to know the damn burrito prices and don't care about the excuses.
If you want to know the burrito price, you open the app/website and look at the burrito price... you don't go to a "Taconomics" website comparing taco prices across a continent. As it stands, there are a number of uncontrolled variables that mean this is not an effective analysis of "How economical is your local Taco Bell?"
