This is my last question.
Wouldn't it be useful, then, to have different methodologies—the official CPI that you're using that accounts for substitution, but also one that's the traditional way before the changes were made?
I don't know when that was agreed to in the U.S. It was the U.S. Bureau of Labor Statistics, I think, under direction from Congress, that changed it from a basket of goods to a cost of living standard. Wouldn't it be useful to have both to alleviate some of the concerns that consumers have?
