When we measure the basket, we use scanner tapes coming from the supermarkets and the grocery stores. We get from these scanner tapes the product that's being sold, including the volume of the box or the weight of the box. We will adjust that purchase to a standard weight, so that we're comparing apples to apples over time.
In that particular case, if we have so-called shrinkage, with a smaller box of cereal being sold at the same price, we would reflect that as inflation.
