More of interest are these two claims which are
not both true or both false:
For every x there is u < x.
There is u < x for every x.
The latter is close to my function:
There are NUF(x) u < x.

 From ∀x∃U to ∃U∀x is unreliable,

There is no from to. NUF(x) is so defined.
For every number of unit fractions NUF(x) gives the smallest interval (0, x).
