If you really want to spend the time on figuring it out, then examine the difference in scale between the bodies positions, velocities, accelerations given different model timestep values, what happens during the squaring summing and rooting, multiplying by G of those values and also even (because i have looked into this before) the subdivided timestep values involved in tempering this models data, so it becomes a perfectly stable quantised version of its anologe values (with no need for the kind of corrections Runge-Kutta is notable for) That link is very intresting to me thankyou. You can notice that it includes some quite simple integration schemes as 'symplectic' (basically means stable without need for gross correction)
