comment Term for a bad quantity ranging between 1 and infinity
The reason I use an "inverse efficiency" and not efficiency is that most values of $Q$ are whole numbers, and they look much better than fractions. E.g., it is easier to distinguish $2$ from $3$ than $\frac{1}{2}$ from $\frac{1}{3}$, because the font of the main number is twice as large.

comment Term for a bad quantity ranging between 1 and infinity
Your guess is accurate - $Q$ is indeed "inverse efficiency" - a ratio between a certain maximum possible value and an actual value. Since this term is used a lot in the paper, I am looking for a shorter term.

comment How to approach a minmax problem?
The general geometric problem is this: math.stackexchange.com/questions/851185/how-fat-is-a-triangle Although there are other solutions, I still want to know how to solve optimization problems such as this. It seems a useful feat to have :)

comment The number of lattice triangle subdivision.
Why $N(1,2)=6$? Can you add a drawing that shows how you calculate this?

comment Geometry and land
Interesting, thanks! Though, from Herodotus' citation, it is not clear what geometric problems were involved in the measurement.

comment How fat is a triangle?
Thanks. Although this is not an answer to my exact question, it is most useful for me as it allows me to plot the slimness factor as a simple function of the angles. Here is what I made of it: desmos.com/calculator/zsn0i0hvmr

comment How to solve the trigonometric equation $\cos17x=20\cos x$?
If all you need is the solution (without a formal proof), you can just graph the two functions and see where they meet: desmos.com/calculator/qb6n7onsig

comment locating any point on a real number line
In every step $n$, your grid has intervals of size $10^{-n}$. Hence, the distance between your number to the boundaries of the selected interval is at most $10^{-n}$. When $n \to \infty$, this distance goes to 0. Hence, after an infinite number of steps, the interval contains exactly your number.

comment locating any point on a real number line
If you have infinite time then yes, you can find any point on a real line by your method.
