In the previous papers, we tried to analyze the complete loop counting functions that count all the loops in an infinite random walk represented by digits of a real number. In this paper, the consideration will be restricted to the partial loop counting functions $V$ that count the returns to the origin only. This simplification allows us to find closed-form expressions for various integrals related to $V$. Some applications to the complete loop counting functions, in particular, their connections with Bernoulli polynomials, are also provided.
