I used to be rigidly honest with my report, even taking off the coffee break time etc
This made it embarassing for one Elder, our "Book Study" overseer as it was then, he had accompanied me out in the service every time for a month, not doing any more or less than me, yet my report was so much lower than his.
He tried to tell me to bump it up a bit, as I was an M.S, saying, "well look how long you are away from home each time you go out" etc, but I replied "I thought we only reported from the first door to the last". He wafffled some more about how my report should reflect the effort I am expending.
Eventually , just before I stopped FS all together , I stopped caring about it being accurate, but it wasn't overly inflated, I just stopped writing down the details, so took an eduacted guess.
We had some Elders that hardly showed their face in the DtoD work, but reported 10 or 14 hours a month, mainly "informal witnessing" apparently, yea right.
