I may not fully understand what you are asking but if I am correct, I am a Sagittarius and can't figure out for the life of me why I attract cancer and virgo's go figure? I am suppose to be compatible with leo, aries, gemini, aquarius, then libra, in that order. And of course we are all suppose to be compatible with our own signs. But I have yet to really understand all of astrology, not my forte.
my favourites are sagitarians, sooo compatible for any kind of relationship.
worst for me capricorn,but for some unknown reason am a capricorn magnet !!
ps i'm aries.
