Now that I've figured out how to post the chart, I've thought more about it and it is not clear to me that the chart helps. The statistics that we referred to originally, provided probabilities like: above some level, there was a 90 percent probability of the GMI being X percent lower in N months. Now that I see the chart for the 20 years for 1960, it is not clear to me that any of it is meaningful; so I'm going to forgt it.
I do have some info that may be of interest but I want to be sure first that I can post the right charts. test:
