OK, I'm back, sorry.  The information definitely needs to be in the article, however, we should make sure that we have the numbers correct.  Once we agree on the numbers, we just need a simple statement to the effect that the survey performed under the auspices of AA suggests that XX% of newcomers leave after 1 month and that, after 1 year, XX% have left the fellowship.  In addition, I would add a sentence as to how this was not a very rigorous statistical approach (if, in fact, it was not).  All that I was objecting to is the bit about using 3 month to 12 month attrition as if there were some logic to it.  Too bad we cannot use the graph and an explanation.
