How social are the people trying this? Do any of you have jobs with scheduled anything? Go to classes or events that are 2 hours long? Having "more hours" a day, if works would be great but it seems to be insanely inconvenient for anyone who spends a lot of time driving or wants to watch a movie or go to a concert or needs to work with people. Assuming the final "quality" of the hours you have ends up on average unaffected by sleep deprivation, the extremely weird and disciplined schedule still seems terrible to me, and I don't even have a job that is particularly scheduled. This strikes as something that gives you more lonely hours at the cost of wrecking a lot of the hours you might have with people. This is less of a problem if you're in a community of people doing this but still seems pretty rough.
