If you can tell me how to do it, I'd gladly do it.
We always do it on the best available data. By definition, the data is old by the time I give it to you. We try to be prospective. We try to look forward. We try to spot trends, to anticipate, and to take that in, etc., but it is not a science. There are an awful lot of assumptions that you have to make, and you can be dreadfully wrong, as you know--in the Internet business especially.
