What do you mean with a human author? Sorry you actually lost me on this. Student logic is the skill of taking school tests right? Cause outside math i had very low grades.

I rely on the same mathematical logic but the calculation is done intuitive, like a gut feeling. Thats not the “reverse engineering of formulas” i talked about, that i just did because school expected it of me. But it relies on this very useful ability.

As you use math intuitively you become more intuitive at it, honing the ability. School did not provide a platform to do so while it makes you better at normal calculations as well

The example i gave that does best illustrate it is seeing the sizes of things without having to check labels, markings or actually measure. Especially useful for domestic jobs Like hanging up a mirror on the wall. Or when visiting stores like an ikea.

Another term I believe for it is eyeballing it. But i cant see how you think it isn't useful outside of schools. (Pun intended)

I have been outside school for more than 10 years. I use all kinds of mathematical principles on a day to day basis (part of how i perceive the world) but solutions requiring specific formulas pretty much never happens and when it very rarely does happen (i think i used Pythagorean once 2 years ago), i just google it.

Oh its also super useful in video games like Minecraft where you have to do a lot of math but cant be bothered to take a calculator. But video games aint real life so it doesn’t count.
