In mine that would be a big fat ZERO.
There have been a handful of teenage baptisms of JW children.
One that really was a foreign language group transfer.
But in the last ten years - there has not been one single convert from the D2D ministry.
BTW - my congregation has had over 10 pioneers (real ones that actually do D2D, including elders) for the last decade.
Not one. 10 x 70 hours a month x 120 months = 84,000 hours ... results = 0.
Also most of our pioneers are pretty good at the door - some half way decent teachers. One is sub CO and another often is called to teach ... wait for it ... pioneer school!!!
The 84,000 does not include all the aux pioneers and other publishers - many of whom do way more than the average.
Again, that's 10 years - 84,000 hours - 0 results. Good teachers too - what does that say about the product?
