Your math may be rough for conversation only, but you cant just subtract 20 year overlap. They need to be annointed AND overlap. The likelihood that a 20yo is anointed is low.
luckynerdprepper: Thanks you for the analisis.
My calculations, posted multiples times here, and ignored as too nerdy, are based on the remarks by David Splane on the famous chart video.
He cited Fredrik Franz as the gold standard of underlapper, overlapper groupy partakers.
F.F was ~ 20 in 1914, anointed ( most christians in that era were anointed at baptism, perhaps still are ***, not at the memorial btw) and died in 1992 after ~ 80 years of "service". now:
David Splane mentioned that there exist no doubt older, longer serving partakers worldwide ( this is not about GB warm buddies only, but involves the count of all the last generation of thousands of partakers/ anointed) so:
Frederick F gets us to 1992 , his modern day alter ego to (>1992+>80) = > 2072, David's supposed supercentenarians easily to 2075.
allowing for a few month (for fight training, cum bridal affairs) between the rapture of the the parting partaker, at the beginning of the GT, and the combat in heaven at the BoA. so,
taking the good man, DS at his good word, 2075 it is. with anniversary celebrations still allowed by wt :
happy centennial .
***likelihood of finding male virgins among the young is greater Rev. 14.
sealing of remnant is done by angels, and their lips are sealed too Rev.7.
