I looked at a lot more than just 2007. 2007 was the one that ended up having the big change. I looked at a large range that included 2007 because other data from other people pointed to that year as being a potentially pivotal year.

If you'd like, I can share some spreadsheets with you to see if there is something wrong with what I did. Similar to looking at sales, if my sales are going something like 50, 50, 50, 50, 100, 100, 100, 100.....I think we can probably say that something in the middle there changed. Or, am I still not getting what you are saying?
