Jam and Fink-
I´m with you both on this one.
In the late 80´s Dan Skinner was our CO. He opened his meeting with our elder body, with this unpublished statistic from the WTS - that there were (as of that time) as many disfellowshipped as there were actual witnesses.
A sobering factoid I never forgot. The percentage today is likely much greater as a poster surmised.
