Dragon/Capricorn 1976 + Monkey/Taurus 1956 = Perfect match?

I'm a Taurus Monkey born April 21 1956, she is a Dragon Capricorn born February 25 1976. Everything I read says more than perfect, except Vedic astrology where we scored 17.5 on a rudimentary test. Conclusion was that we are a good match but a marriage probably would not last long and to avoid the marriage. This is not what I wanted to hear. Should we dig deeper to find out if this basic assessment is flawed and we could get a better result?
