Any machine takes time to accelerate up to the optimum programmed feed, the smaller the segment, the less chance the machine has to do what you asked it to. Longer segments are kinder on the machine, and on the tool and produce a much better finish. On short segments you may never reach your ideal speed. As for accuracy, my CAM program does a very good job on arc approximation, it's programmable for arc tolerance and can produce smooth running code with a finish better than I can accurately measure if it were done with exact stop and short segment code.
