Unfortunately I am not a demographics expert, so don't know the percentage of annointed we could expect to die each year.
It is possible to work out how many leave the borg each year by playing off the baptisms against the previous years average publishers.
I would like to play off the number of annointed expected to die in the group in twelve months, against the partakers following year, and thereby work out how many started taking the emblems each year, from the time it hit only 10 000. (late 70s)
I actually wonder if anybody with the available figures back to Bible Student days could calculate how near to 144 000 the figure of new partakers gets in the course of the last 130 years.
