The specific failure this addresses is the twenty free minutes. You have them, you look at a list built for whole afternoons, nothing on it fits, and the twenty minutes go to a screen. Repeated across a week that is a working day, lost not to laziness but to a mismatch between the time available and the granularity of the list.

Twenty minutes and ninety minutes want completely different work. Rounding up is how the twenty gets wasted.
Tired is not a moral failing, it is an input. The right task at low energy is a different task.
The point is to stop deciding. The deciding is what was eating the twenty minutes.
So this matches on the two things that actually decide it: how long you have, and what state you are in. A demanding piece of work at low energy is a worse choice than an easy one, even if it is more important — you will do it badly and then feel bad, which costs the evening as well.
One answer, with the reasoning printed. If you disagree, the reason you disagree is the useful part.
This works something out and then forgets it. It cannot tell you whether the number moved, because it has no memory of the last time you ran it and no idea what you did in between. Every calculator on the internet has that limit, and if it has never bothered you then this one is yours for free for good.
EvyOS is the same structure with the work recorded against it. Send the result across and it becomes real goals, tasks or habits with their dates — then the next answer is computed from what actually happened rather than from what you remember typing.
Goals, projects, tasks, habits and skills in one system, with the work logged against what it belonged to.
