Hello Jay, the broadcast dates for the three episodes scheduled to air covering the SuperNationals event will be announced a week or two after the race is held. The production staff dictates the coverage in each of the episodes. SpringNats and SummerNats were contracted for two each, while SuperNats has three I believe. It costs no money for CBS to re-air the episodes, thus they replay them over and over. It is great exposure for the sport, and that is what the program is based around.
