It would be cool to research those ideal times. It is obvious that if one sticks to the hard coded ideal rest/wake times one is much more energetic, productive and more focused but I'm curious how big the difference is. Around 11 am I can wake up and cycle 200 km or run a marathon starting immediately. If you ask me kindly to run 100 meters around 6 am your life is probably in danger.
