I don't find it insightful because for me tasks that are ToDo are not like sine waves.

I am also not a person that gets annoyed by cleaning dishes or brushing teeth. I just do these things and I accepted that these are time costs that I cannot do much about.

Not brushing teeth - getting even single infection from rotting tooth would cost me much more in terms of wasted time than brushing twice a day.

Just like trying to cut on sleep time, you might get away for 3-5 days sleeping less but then you will have to pay it back with interest.

I think it is mostly difference in approach "unrealistic" trying to schedule and squeeze in as much as possible - vs - I have bunch of stuff to do, let's see how much I will be able to finish and anything that drops goes to the next day or ends up never done because if I did not do it and no one complained (even myself) it probably was not that important at all.
