Most of the above charts are illustrated with their Precise Progressed Phenomena. The PPP are major secondary progressed appointments or progressions leaving marks behind. They are also true progressed charts and are even easy to calculate with any good ephemeris with aa aspectarian including the hours of the conjunctions.
The PPP to look for are the charts of any important conjunction occurring between progressed planets in the period that preceded and followed the actual birth: the usual 3 last month of pregnancy for the conversed and the 3 first months following birth for the direct Secondary progressions.
By important conjunctions I mean only the conjunctions that are tight by declination, also called parallel conjunctions: less than 1° apart are the strongest, but less than 2° of separation is still tight enough. There are usually only a few of those in a life. Prenatal or progressed eclipses can appear in the list. The closer to birth the events happen, the more significant they are.
These major appointments of life leave traces: the zodiac degrees where the tight conjunctions occurred continue all life to carry their meaning, to the point of being receptive to progressions and transits. In other words, they don't need dating to be interpreted, as they are there and valid from 3 months old.
To make sure you understand the technique : the major Transits occurring during the first 3 months of life correspond to the major Secondary progressions, called PPP for ‘Precise Progressed Phenomena’ or planetary events. These events show the Radix focused becoming. The Precise Planetary Phenomena 1920-2030 collection was created among other reasons, for this purpose: all Lights and planet conjunctions are detailed with the precise declination for each planet and for their distance apart.
