The report is supposed to be only witnesses who turn in time regularly. So those out for years are not included. Strange though, before I left they started putting names of people who had not been to meetings in years back into bookstudy groups.Entire families in some cases. Some bookstudys would have 15 or 20 people listed but only 6 would be there.
The number of partakers is relevant to their doctrines because currently they believe armageddon will come before all annointed are dead. On account of the chosen ones(annointed) those days will be cut short(tribulation)
That is why I feel they are being squeezed by time. They still need armageddon to come soon or they will have to start changing major doctrines. If they can wiggle the great crowd to become the chosen ones by extension somehow they may get by. The great crowd can run the org, serve on the governing body, etc.
I saw a quote from a WT where they quietly applied the scripture about the glorious ones, which had always been the annointed elders, to elders in general. It may be a start. In any case requiring the org on earth to be run by annointed only can't last much longer.
