Though I rarely get it, I definitely feel my best after 12-13 hours of sleep. I've never understood how the world seems fine with just 7 or 8.

If I sleep over 6-7 hours I find it incredibly difficult to get to sleep the following night. The problem for me is I am perfectly happy sleeping 12 hours :) If I actually obey my alarm and get up after 6 hours of sleep that seems perfect to get me through the day (without caffeine) and fall asleep quite quickly the next night.

  Same there. If I sleep as much as I want (8-9 hours), my day tend to be 26+ hours. So I'd go to bed later and later. 7/17 formula works fine for me. I feel dizzy with 6 hours of sleep only though.

    That's exactly my problem. A few years ago I tried to follow that pattern. I got as much sleep as I liked (8-9 hours usually) and went to bed when I was tired. It just got later and later until I went to bed just before sunrise and woke up just after sunset. Missing sunlight was actually quite horrible so I ended the experiment after that!

"I definitely feel my best" A careful read of the article indicates its from the perspective of maximization of lifespan and maximization of short term productivity. Why must they both be the same or have anything to do with each other, beyond numerological coincidence? You're talking about a completely different metric, which is quality of life. From personal experience in .mil my "combat effectiveness" for uncle sam probably was maximized by only being able to sleep for about three hours per night. I would not wish that hell on anyone. There should be more to life than merely making someone else richer at the fastest rate you're capable of, or being the last guy in your cohort to die, while suffering in agony.

I don't have any sources but for a lot of people this seems to decrease with age. I'm 28 and I can still sleep for 10-12 hours if I don't have any reason to get up, which is rare. However, I don't think my dad can actually sleep more than 8 hours if he wanted to.
