Davison is done by adding up the time & date plus the Lattitude and Longtitude of two persons and then dividing it by two to come up with a new 'birth time' for the couple.

Davison is used to counter the fact that the composite chart is a 'fake' chart, as in, it does not exist in real world terms and therefore it is impossible to do progressions or transits for a composite while it is possible to do that for the Davison.

I was just wondering what people who have experience with both would suggest to use.
