No. I find composite charts insignificant.
No doubt I'll ruffle everyone's feathers again with my logic, but there ya go.
I understand that in astrology, being an art, and genuine astrologers being artists, the concern is over that which is 'significant', not that which is deemed 'accurate', leave that to the astronomers and mathematicians, so I found that I could only answer the question in terms of what I find significant.
I much prefer relationship, or 'Davidson' charts. A composite is not a real horoscope, it's a chart, but not a real horoscope. A relationship chart represents a real configuration that actually took place in the skies around us at a specific time and place on earth, this in itself makes it somehow more valid to me.
In a composite, we get configurations that are simply not possible, such as the Sun being in square with Venus for example, which can never happen, and the very fact that certain configurations can never actually happen tell us something about the nature of the relationship between those planets.
It is very perplexing to me that in the relationship section we see nothing but composites, composites, composites, never any relationship charts.
A relationship chart, takes the middle time and the middle coordinates between two person's birth place and times, and so it symbolises where these two people 'meet in the middle', in terms of time and space, not simply in terms of space alone, and only the middle spacial distance between planets in the charts, not space in terms of the actual, real space between the two people in the physical world.
In the relationship chart, the older party takes the ascendant, as this person will already have been alive at the time when the horoscope that the relationship chart represents was actualised. So this older person takes the ascendant, the younger the descendant, and we can differentiate between them in this way.
This is very interesting in the case of twins, where we can differentiate between them quite clearly in seeing the first born in the ascendant, and the second in the descendant.
Relationship charts represent a real horoscope, the composite chart does not, and features impossible configurations between planets, which are impossible because they tell us something about the nature of the relationship between those planets. I think that the obsession with composite charts, is a symptom of the material, mathematical and therefore anti-spiritual, anti-astrological, obsession of our era.
