I'm curious about what warrants these additional congregations in the first place. With 275,581 baptized, this amounts to an average of 2.38 additional publishers per congregation (using the 2014 number of congregations, or 2.42 using the 2013 number of congregations). This certainly isn't enough to warrant all these new congregations. It's not as if large numbers of people are being converted in a local area to the point where new congregations are being formed purely out of new converts.
Looking at it another way, it makes a little more sense:
dividing the newly baptized into the newly formed congregations gives us 173 new cultists in each new congregation. Of course, the effective growth would have to take in account the number that stopped publishing to get the true net growth. Once you do that, you're down to about 106 new ones per new congregation, which is a pretty typical congregation size.
One thing that's for sure - the big J definitely isn't "speeding up the work" and the need for new KHs has dropped significantly in the past couple years. This stands in direct contrast to all the cult's raving on about how many new KHs are needed in order to drive up donations.
