Mr. Devanshu
You should not ask this question without giving the details of both. Date of birth, time of birth and place of birth are required. If you go with the insufficient data, it will not give correct results. My friend who is an professional astrologer said that there are people with high score and they are separated and those who have less marks, are living happily. It is his observations.
The score is attained by adding 1 to 8 totalling to 36. It is not clear how the scientists assigned the numbers. Nadi is seen for health issues. If there is no compatibility, the health issues may rise.
For happy living, we have to check the characters, vices if any, of both the guys with proper local enquiries. Through astrology we have to check the compatibility of both, their mind sets, whether they are capable of producing children, livelihood, compatible for conjugal relationships etc. Even if the score is low, if all the features are good, you can proceed for marriage. In this way we check the horoscopes in KP system.
So please provide the details. Our vedic astrologers will guide you.
Good Luck
