  Quasi-Stationary States of long-range interacting systems have been studied
at length over the last fifteen years. It is known that the collisional terms
of the Balescu-Lenard and Landau equations vanish for one-dimensional systems
in homogeneous states, thus requiring a new kinetic equation with a proper
dependence on the number of particles. Here we show that previous scalings
described in the literature are due either to small size effects or the use of
improper variables to describe the dynamics. The correct scaling is
proportional to the square of the number of particles and deduce the kinetic
equation valid for the homogeneous regime and numerical evidence is given for
the Hamiltonian Mean Field and ring models.
