I'm with you on this. I think it's one of those things that makes for a good/funny-yet-way-embellished (if there is even a kernel of truth to it at all) "work story" and the guards just ran with it.
Who confessed he flogged the bishop between 7-10 times a day on average to me. It is possible, but yikes, that is scary if it's true what Jeffs is doing.
I suspect the guards merely witnessed Jeffs going through the motions that many times over the course of the day...I doubt that he actually blew fifteen loads of baby batter.
