On the basis of the most recent (1997-2002) VMDB records, we provide an extended analysis of the meteor showers collectively called the Aquarid-Capricornid complex - the Southern and Northern delta-Aquarids, the alpha-Capricornids and the Southern and Northern iota -Aquarids. Our analysis covers two months (July-August) of meteor activity. We present a set of updated shower parameters, including visibility periods, population indices and activity levels. We also discuss a number of factors that may significantly alter final activity estimates obtained from visual observations. These are in particular the shower association, zenith attraction and the role of the zenith exponent.
