Abstract
In this paper, there are two sections. In Section 7, we simplifythe eigenvalue-based surplus shortline method for arbitrary finite polysquaretranslation surfaces. This makes it substantially simpler to determine the irregularityexponents of some infinite orbits, and quicker to find the escape rate toinfinity of some orbits in some infinite models. In Section 8, our primary goalis to extend the surplus shortline method, both this eigenvalue-based version aswell as the eigenvalue-free version, for application to a large class of 2-dimensionalflat dynamical systems beyond polysquares, including all Veech surfaces, and establishtime-quantitative equidistribution and time-quantitative superdensity ofsome infinite orbits in these new systems.
