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