Jeff Duff - Scientology Service Completions

Note: Preliminary analysis suggests that about 60% of people who try Scientology do only a single course or service, that 80% of new members become inactive within 2 years, and that 65% of those who reach the level of Clear become inactive within a year after doing so. The older a list, the more likely that a person listed on it is no longer involved in Scientology.
