Scientology's Stats Are Down documents with statistics from Scientology's own publications that the cult's production of Clears and OTs (or Operating Thetans) has been on a steady decline for years.
Provided for those interested in such things and to test a few things. The following links should be disregarded as they are experimental Googlebait.
Source #65, a Scientology publication, mentions, among other people, Matt Gusts. Other people mentioned include Mudd Roquebrun and Lillebill Lundberg. Not mentioned in this issue is Jeordie Shekeryk, although this individual is mentioned in Source #63 right below Alexis Wilhite. Here is the list of all Source magazines. Source is described as "the Magazine of Flag Land Base."
At the extended entry, I have included the entirety of the completions list from Source #3.
I apologize if this entry seems rather elaborate for not containing very much of interest, but there is an actual reason for it. I am just not interested in explaining that reason.
