As far as I'm concerned, it's settled. As I've tried to explain, I use the term "net decrease" in its broadest possible sense, i.e.
Net = after deductions
decrease = a reduction in figures
In this case, the 'deduction' is the baptism figure, or my "growth indicator". In most countries, once this is taken from the gross increase (difference in publishers from one year to the next) you have a "net" (after deductions) "decrease" (the number goes down).
I think the above methodology is what confused most people, including myself. I visualize it like this:
Let's say you have a congregation of 100 publishers at the beginning of the service year. For simplicity's sake let's say no one dies or moves. During the year little Johnny and Susie become publishers. However, Bro. Fader becomes inactive and stops turning in time so he is no longer counted as a publisher. At the end of the service year the congregation now has 101 publishers, which is a 1% increase. It is a net increase of 1 in the number of publishers.
Now during this same service year 5 people in this congregation decide to get baptized. They are teenagers and progressive Bible studies who had become publishers in previous years. At the end of the service year the congregation still has 101 publishers, a net increase of 1, or a 1% growth rate.
However, using your methodology and terminology above you would take the 5 baptisms in the congregation and deduct it from 1, the "gross" increase in publishers, resulting in a "net" decrease of 4 for the service year. That makes no sense. How can a congregation which grew in publishers (from 100 to 101) have a net decrease in publishers?
