Who told you the softwares do match horoscopes automatically. It is a set of programs written by astrologers to do the matching mathematics with the aid of computers. Even this question you are raising and our answering are all being done with the help of computers. The problem is with half baked astrologers who always interpret horoscopes at variance from others primarily due to changing moods and inadequate exposure to the science of astrology.
Yes I can match your horoscopes and give you the exact percentage of match using my own software using computers if you are interested, not as a free service but you will have to pay for the services. Contact me at email@example.com if you so desire.
