When you're doing your study, or your group of studies, what is the methodology to compare doughnuts to doughnuts, as we say here?
We have different densities. We have different sizes of countries. We have different levels of usage. I think usage in Canada is about 400 minutes a month or something, and I think it's much less in some countries in Europe.
Is there a way, through your methodology, that you're able to equalize those differences, or are they actually highlighted within your study?
