Journeyman: Admittedly, it might seem a bad idea to imply a lot of your members are deluded or even mentally unwell(!) as they hinted
This might be a good reason to drop the literal number. I think they said this (about partakers possibly being mentally unwell) in the hopes of getting people to stop partaking, so that the number of the remnant would drop again. Then they could go back to saying "look at the dwindling number of partakers! The end must be close!"
But the number has just continued to climb. We went from a low of around 8,800 to more than 22,000. The number is an albatross now; it is difficult to reference it without being reminded that it has increased significantly after the change in 'understanding.' The ship has sailed.
A change that makes the number inconsequential might be the first step to dealing with the problem. The eventual last step would be that they could ignore it, since the number would no longer matter. The concept of two groups (one heavenly, one earthly) could still be used, without the issues that a hard number creates.
