tbf OP did mentioned it varies from genetics to genetics. 7-7.5 hrs is actually good spot. Mostly 8 hrs is recommended. For me 6 hrs is enough, but it also depends upon the work you are doing in your day to day life.
The goal is just plain wrong. You don't optimize to shorten ur sleep, u optimize to improve ur sleep and rest pattern which might happen to shorten ur sleep.

That is correct. The goal is to find ur best. Not defining a number and going backwards to justify it.
Glorifying sleeplessness is extremely bad. The author might be in sleep debt himself. Also we need to consider the throughput as the performance varies. When I was tired I would not be able to code as efficient.

Totally agree with this. I'm surprised how even health professionals prescribe an average value as something to work towards. Heck, they even give the same 8 cups of water a day advice to 50 kg females and 90 kg males. What an absurdity. Anyways, people should find the optimal amount for them by observing the outcome.
My sleep sweet spot is also around 7-7:30 hours.
I am typically a good sleeper as in don't wake up etc.
On days where I sleep more or lay I I often feel less energetic.
Then there are also the cases when I go to bed early and wake up early by myself 'ready to go'.
I also like the suggestion to do the important thing first in the morning. So far I have not found a way to get around the morning chores, lunch prep, kids, dog etc. I know the theory (pre prepare, do it fast, be organised) but doing it is something I need to work on.
