I know most of us have probably figured this out already, but remember the good old days where you could only count full hours in the ministry?
Then one of the GB get some "new light" from their ass and proclaim that they lovingly will allow people to report 30mins, then even 15mins of time. This was, supposedly, so that the old and infirm could have a joy in the ministry and report what little they could do. I suspect, nay, i am confident, this is just because all those 15mins and 30mins add up to hours and hey presto you have hundreds more hours to boast about in the new yearbook! (Even as a Jdub i saw through this shit.)
Then... every so often (usually around memorial or convention time) they allow auxiliary pioneering to report a lot less hours yet still be considered pioneering. So lots of Jdubs in full time work (myself included) jump at the chance to "reach out" and auxiliary pioneer with bogus hours. Again, those numbers add up. So it's not that the ministry has increased, it's probably stayed the same or even dropped. In reality they've just cashes in all the loose change and added it all up.
Then... you're now able to count family worship, studying with an inactive one, studying with your children etc etc - and hey presto more hours for the year book!!
It makes me glad that i very rarely filled in a report slip truthfully. Yes, a blank report slip was my canvas. The rule of thumb was how many hours did you really do? multiply it by 10 and divide by 3.
