'Sincere ones' - these are JWs like my mother who tow by the line and sincerely put efforts in their preaching work and count the actual time they preached, not like the fakers. She believes that nothing has changed because Jehovah will anyways know how much time you put in the work and will reward people for that.
It's her reasoning that if Jehovah can change the circumcision requirement and first-century Christians accepted it, who are we to complain about such a measly change in time reporting? and even if people (elders too) are slacking in accepting it, Jehovah will correct it too the way he corrected Peter through Paul.
Surely there are many who have questions, even the Elders?
Of course, people will have questions, but everyone is waiting for the annual meeting video that will be uploaded on Nov 6. and even if people don't accept then as the current CO said to the BOE last week - you either shape in or you ship out.
