Yes, it's about whether you're making progress. If you look at this century—and you alluded to it, Rebecca, as well—in the past there were returns of 100 million. Now we think that 20 million or 30 million is a “record run”; I have heard that referred to. It's definitely a high run. Now, when we look at a million returning, when you do the overall trend from pre-1950 to now it's obviously not as strong as it was.
Are we making any progress at determining why that is?
