I haven't heard from the Dupuy Institute in awhile. I wonder if the report will be released into the public domain. At first glance, I'm reminded of the old saying, "Numbers are like people. Torture them enough and they'll tell you what you want to hear."
It would be interesting to see what makes into the column as an insurgency and what is left out. All in all, however, it sounds like the study is just saying, "stick it out and let time take its course. odds are you'll win."
