A translation surface is given by polygons in the plane, with sides identiﬁed by translations to create a closed Riemann surface with a ﬂat structure away from ﬁnitely many singular points. Understanding geodesic ﬂow on a surface involves understanding saddle connections. Saddle connections are the geodesics starting and ending at these singular points and are associated to a discrete subset of the plane. To measure the behavior of saddle connections of length at most R, we obtain precise decay rates as R →∞ for the diﬀerence in angle between two almost horizontal saddle connections.
