I use this program called astromart8.2 and you can do synastry charts with it and it shows values next to each aspects two people form and the total on the bottom you should download it and check it out. I just believe that the synastry chart is more accurate because I think that I was primarily relying on composite charts and relationships between me and other people just didn't seem right . I guess I suppose that I have to use the two of them together and not just one. Another example is lets say me and a ex girlfriend form a sun square sun aspect with this huge value that stands out and your saying that its possible that the aspect in a composite chart would turn into a good one? So that means I shouldn't believe it is truly sun square sun that it may be sun trine sun and something good.
