What I gathered from the post was that it was more of a challenge to see how OP would do without any sort of stimulation. I think that's the fundamental difference here, OP's experiment is an extreme, where you go to no stimulation at all, while the Sabbath is more of a shift in sources of stimulation. Still valuable, and a lot to gain from it, of course.
