to answer my own question: Wt could maintain, that any partaker under 54 years.....
sorry, accept my correction please: The gold standard anointed overlapper would be only 46 years old today. how to verify? :
Frederik Franz was 21 in 1914. his modern counterpart would be born in 1971, be 21 in 1992, FF's year of death. That then 21 year old anointed bethelite would be 46 years young this year, attending the GSM. and looking forward to live to nearly 2075***, to celebrate the 1975 centennial. ha ha.
Any partaker over 36-46 year old is potentially a legitimate second grouper, wt's denial notwithstanding.
Wt is wrong to rush the end based on partaker couts. If an "anointed" gets the HS at baptism, as was customary in apostolic times, that 21 year old could be instead a pre-teen jw baptismal candidate customary today, so, make that 36.
***David Splane opined that Frederik Franz would be no means the longest living anointed of the under- and overlapping groups.
