Mr. John McCarthy:

It can be used as a guide but it's not the be all and end all. I would accept your point that there are limitations of looking at the historical experience. As I mentioned to Deputy Higgins, you know, we had the historical experience of the Great Moderation. That looked as if everything was great for the next 20 years and so forth, suddenly things changed overnight. So, it can be used as a tool but, you know, there are, there are limitations and there are health warnings with the tool.
