For software stepping, the base thread is typically around 20 us, and so a jitter of even 5 us is more than noticeable. But, on a typical servo system (or a stepper with external step generating hardware) there is no base thread and the servo thread runs at 1000 us, so the effect of a 5us jitter is insignificant. As long as the worst-case jitter never exceeds 20 us, servos should run flawlessly.
