This is all very interesting, Brian, but I'd like to point out that according to the lidurature that comes with the holosync tapes, most people on the program achieve 4 - 5 hours of sleep. This is a combination of the 1 / 1 1/2 meditation (the last half an hour or hour delta) with the floating tape designed for sleep. The material was written some time ago - I'm not sure how well it held up.
He diesn't say whether or not you still need power naps, or if you sleeping needs are entirely satisfied.
