Extremely small delay times may cause the MARQUEE to scroll more than once during each screen retrace interval. It is wasteful of the CPU resources to scroll the MARQUEE faster than the viewer can perceive the changes. A longer delay and greater scroll distance is more efficient although it may appear jerky for extreme settings.
