It’s also noted that one could learn TTATT by careful study of the NWTs cross-references.
Like the 1984 cross reference that linked the "faithful and discreet slave" in Matthew with those spoken of in Daniel as "having insight who will be made to stumble" in the time of the end.
Or cross references that linked generations as a definite length of time, not some overlapping period of people whose lives overlapped other people lives that could be stretched out to mean something totally different than what was written.
Each time they trot out a "refined" understanding it seems to knock another leg out from under the chair supporting old understanding.
