There should be some interesting conversations if they start asking each other how many hours they did the past month.
Ugh. Don't get me started on that. Back when I was pioneering I used to hate it when other pioneers would ask each other "how are you doing for your hours this month?" or some similar question. None of your damned business! I never dreamt of being so intrusive and nosey to ask others about that, and when anyone volunteered such information (as some do, trying to be boastful or win brownie points, I'm sure) I used to make it quite clear I wasn't interested in that discussion and change the subject. Ok, if someone asked "can you do a couple of hours with me, I need to make up my time" or something like that, it was different, but otherwise it was none of my business and I didn't want to know. I was always uneasy about the over-emphasis on time and hours.
You could be right that this change will make more publishers (especially elders) ask each other that question, dressed up as a desire to help them achieve their personal ministry, but really to try and find out what hours they're doing and whether they feel they're doing enough or not. (The 'correct' answer of course is: you're not. If you feel you're doing enough, you're not doing enough!)
