This paper reports on time-series analysis of 156 pulsating red giants (21SRa, 52 SRb, 33 SR, 50 Lb) in the AAVSO (American Association of Variable StarObservers) observing program for which there are no more than 150-250observations in total. Some results were obtained for 68 of these stars: 17SRa, 14 SRb, 20 SR, and 17 Lb. These results generally include only an averageperiod and amplitude. Many, if not most of the stars are undoubtedly morecomplex; pulsating red giants are known to have wandering periods, variableamplitudes, and often multiple periods including "long secondary periods" ofunknown origin. These results (or lack thereof) raise the question of how theAAVSO should best manage the observation of these and other sparsely-observedpulsating red giants.
