What's that?  Mathematics says that NUF(x) = ℵo for x > 0.

Mathematics is not done by waffling like this.

From this trivial fact you would have to show that there are x1 and x2 >
0 with NUF(x1) =/= NUF(x2).  Since you can't, you should just admit that
your denial that NUF(x) is constant on (0,1] is wrong.

The step change happens in WMaths too.  UF(x) (the set of unit fractions
between 0 and x) is empty when x = 0 and not finite for all x > 0.  How
is this possible when "never more than one unit fractions is added at a
point"?
