The main difference between these different compatibility techniques is math. It is our opinion the Synastry method is the most accurate. The following paragraphs describe the calculations for each particular method.Composite Composite charts are erected by creating midpoints between the two charts. This can be summed up using the formula (Sun A + Sun B)/2 = Composite Sun. Here is an example…Sun A = 10 Scorpio = 220° Sun B = 12 Libra = 192° Composite Sun = 220° + 192° divided by 2 = 206° = 26 LibraRelationship Relationship charts are created by calculating the midpoint in time and space between the two birth charts. Simply erect a new natal chart based on this information. Here is an example of this calculation.Person A’s birth data Feb 24 1974 21:06:00 36N09 96W00Person B’s birth data Oct 16 1971 14:44:00 43N28 112W02Feb 24 1974 at 21:06:00 + Oct 16 1971 at 14:44:00 divided by 2 = Dec 20 1972 at 17:55:0036N09 + 43N28 divided by 2 = 40N05 96W00 + 112W02 divided by 2 = 103W35Therefore
