  By introducing the concepts of "superclassicality" and "relational
causality", it is shown here that the velocity field emerging from an n-slit
system can be calculated as an average classical velocity field with suitable
weightings per channel. No deviation from classical probability theory is
necessary in order to arrive at the resulting probability distributions. In
addition, we can directly show that when translating the thus obtained
expression for said velocity field into a more familiar quantum language, one
immediately derives the basic postulate of the de Broglie-Bohm theory, i.e. the
guidance equation, and, as a corollary, the exact expression for the quantum
mechanical probability density current. Some other direct consequences of this
result will be discussed, such as an explanation of Born's rule and Sorkin's
first and higher order sum rules, respectively.
