Do Love Compatibility Tests work?


There are a variety of compatibility tests using astrological synastry on the web and some astrology programs like Kepler cater for synastry. So I was inspired to experiment with the Café Astrology compatibility ranking system* and came up with my own Love Match test. It does seem gimmicky and crass to invent such a thing, but could such tests be useful?

Love between a couple cannot be measured as such, but harmony or a sparky tension between the connections certainly can. The important thing is that there connections at all, even difficult ones! A so-called ‘Love Match’ test then, can at least be objective and prevent your own love-sick bias from making a silk purse out of a sow’s ear.

The Love Match Test Research

I tried as many famous couples as I could find with an accurate birth time and all the couples I knew personally. I wasn’t surprised Paul Newman and Joanne Woodward scored highly, but when I tried the others it all fell apart. After experimenting and stripping down the score I think I have come up with a formula that sorts out the wheat from the chaff.

I found the aspects that cut it time and time again are the classics. Forget your hyped-up outer planets, deluded Neptune and your karmic quincunxes. Space-dust and glitter! To find a rock solid, mutually supportive relationship that will weather the storms of modern life.

I used Ptolemaic aspects and considered the following: Tight orbs between the Luminaries/Saturn and the relationship planets, also Luminaries/Saturn to the destiny points and AC/DC. I also looked at the Sun/Moon midpoint and Luminaries in the 1st/7th house.

Here is the list of my best synastry aspects. I used this system on both the synastry inter-aspects, Davison Chart and composite charts. Just using the inter-aspects didn’t work for some couples. Some of these were were surprisingly strong because of the weird magic that happens when you put an unlikely pair together.

Love Match Test Aspects

Café Astrology ranks the following as red alerts. These are highly stressful aspects that are supposed to be real “No-no’s”. You can get away with having one of these at the most they say: Moon square Saturn, Mercury square Mercury, Venus square Saturn and Mars square/opposition Saturn.

On the other end of the scale there are the super aspects. I regard these as karmic-contract aspects.  These are top scoring aspects on Café Astrology, but I have added the Vertex conjunct North Node to that list since it was discovered to be significant in long term marriages according to Cosmic Technologies.

I have found it to be significant. Karmic contract aspects are as follows: Sun or Moon in hard aspect to the Sun/Moon midpoint,  AC conjunct the North Node, Vertex conjunct the North Node, Sun or Moon conjunct or opposite Vertex,  Sun or Moon conjunct DC.

These may bump up the score in a relationship that isn’t really long term. These are usually catalyst relationships and their sole purpose is pulling you onto the right karmic path. They may do this for example by splitting up a failed marriage,  or pulling someone out of drug addiction. When this is achieved the relationship ends pretty quickly.

Love Match Test Results

UNDER 17 you get lovers or co-dependant marriages. Charles & Camila got just 11, though they may just be the anomaly. Strong composite charts could offset everything…. UNDER 10 You are getting into very sparse territory and the relationship would most probably be just sexual with very little else.

UPDATE! OVER 40 is not necessarily a good thing. I found very high scores can be indications of  a ‘Dark Cupid’ type relationship. This can also be a a very difficult ‘karmic contract’ relationship that is obsessive and very hard to break from if it should turn abusive.

Goldie and Kirt’s two Saturn red flags glued them together for 21 years before their relationship ‘lost its zip’. Had Mars been involved rather than Venus it probably would’ve cracked earlier. Indeed most of the Saturn/Mars red alert couples have split up. So you see it is not as simple as getting a high soulmate score or feeling doomed because you have two red alerts.

Once you have the score, then you can then look into the synastry and see what is specifically pulling a couple together. You could still have a very high score with someone who you are not sexually attracted to at all, this could be with a best friend or child. This system helps establish if there is a solid framework for the romance and the magic to hang onto. It is also good if you want to compare two lovers when you can’t decide!
