Blondie,
when was the last time these 2 dates were mentioned and correlated together?
You've probably forgotten, but there was a study article this year that did exactly that: it correlated 607 and 1914.

I guess this is some evidence that some WT writers want to emphasize 1914 knowing that lack of mention to it will increase doubt in inquiring R&F minds. At the same time, others would like to diminish its as much as possible, as evident in the growing scarcity of references to the date in recent years.
