It is clearly "speeding up", just not anywhere we are.
The attendance in the assembly's I go to are also declining and baptisms dropping. Only 2 out of 650 last month. One of the talks even talked about how fast the organization is growing and that there is a large demand for more kingdom halls. I'm guessing it must be in some isolated non english speaking country that no one as heard of because its certainly not in this country, and I'm not in USA.
