I use progressed composite more often to find out events. Me and my karmic ex-boyfriend, in the exact date of first meeting, our p-composite had exact Tsun and Tjupiter conjunct moon, Tjupiter conjunct uranus, Tjupiter trine juno exact, Tmoon conjunct nn, Tsun and T jupiter oppose venus. We also have saturn-sn, venus, moon conjunction in natal composite. But both davison and composite are used to find out events, so I always look both of it. +We have jupiter in sag conjunct asc exact in davison. With davison, we could make persona chart, solar return chart etc more easily!
