NUF(x) grows from 0 to more, but at no point it grows by more than 1.
And there is "no point" that is smaller than all unit fractions but greater than 0, so at that point NUF(x) jumps from 0 to Aleph_0.
That is superstition.
Your problem is NUF(x) may have a clear verbal description, but not a mathematical one, as it is based on a false assumption that there exists a smallest unit fraction.
That is not an assumption but it is derived from the mathematics:
∀n ∈ ℕ: 1/n - 1/(n+1) > 0 Regards, WM
