Something I've come to notice when plotting data with the LCG is an up-turn in the number of "fainter than" observations particularly of CV stars that are in fact decidedly brighter than the particular stars ever get at maximum! Multiple such observations (i.e. night after night) by an observer are honestly of no value if there is no hope of ever catching sight of them. It is simply a waste of the observer's time and effort and it escapes me how an individual can think otherwise.
What is further disheartening is the fact that some of these folks should already appreciate and understand this. At the same time, with the ever expanding program of variables followed by AAVSO it making it ever more difficult to cover them all in a satisfactor manner. Observers should really be trying to formulate their observing programs around the stars that, at least during a portion of their brightness cycles, come within the range of their instruments, not looking at stars that can never be seen with the equipment available to them.
