I'm SURE every time the CO/DO comes around, they hit up the people hard to get more time in.
Oh yeah, it was always a pain in the buck trying to get everyone to get their "missing hours" turned in before the CO came around. Basically what would happen is a list was made of publishers who were missing time for certain months. Then these names were given to the bookstudy conductor of each individual and this elder did everything possible to get this time.
Now picture this. Here's Brother John Doe who's missing time for January, March and May. An elder would see him at the Hall and "remind" him to get this missing time in. What would Brother Doe normally do? He'd simply guess. What actually was true was that he didn't really get any time for those months but it was so much easier to write something down just to get Elder Jackass off of his case.
