For lattice QCD with two sea quark flavors we study the static quark-antiquark potential V(R) in the regime where string breaking is expected. In order to increase the statistics, we make full use of the lattice information by including all lattice vectors R to any given separation R=|R| in the infrared regime. The corresponding paths between the lattice points are constructed by means of a generalized Bresenham algorithm as known from computer graphics. As a result, we achieve a determination of the Wilson loops in the range 0.8--1.5 fm with hitherto unknown precision. Finally, we discuss the impact of this approach on the signal of the transition matrix element between two- and four-quark states.
