Krishnamurti Paddhati (KP) :

 
Krishnamurti Paddhati (KP) is an excellent method of astrological predictions conceived, created by The Great Indian Astrology King, late Prof. K.S. Krishnamurti. As you must have experienced that accuracy of the time period of the events is difficult when one uses Vedic/Traditional system, but, KP can give you a precise 'YES' or 'NO' answer astrologically to your questions. To overcome the above and similar short-comings of the conventional vedic system, KP comes as savior. KP is different in many ways from Vedic/Traditional method. The difference between Traditional method & KP is same like the difference between Allopathy & Homeopathy.
In case of Twin births also, the horoscope remains almost the same as per Vedic/Traditional method, on the other hand, as per KP, the horoscopes changes if the difference of time is + or – 5 min. This is the reason that the birth time should be correct as far as possible.

Major Differences From Vedic/Traditonal method :

KP system gives importance to the Constellations / Stars / Nakshatras divisions of the Zodiac which is obviously the most desired for precision.
Further it divides each Constellation / Star / Nakshatra division into further 9 subdivisions called 'SUBS'. These sub divisions are not equal divisions, but are as per the Vimshottari Dashas Divisions System.
K.P. System uses K.P. Ayanamshas as opposed to Lahiri Ayanamshas mostly used in Vedic System. The difference between two is about 6 minutes (Kala).
This system uses Cusps that is house/ bhav beginnings like Western Systems, as opposed to Vedic System which uses House Centres i.e. Bhav Madhyas.
This system uses Placidus House system.
The planet in it's dasha gives results as per it's Nakshtra-Swami (Star-Lord) rather than the planet itself.
Whether the above results will be benefic or malefic will be decided by the Planet's SUB.
Hence Planet is represents the SOURCE, that Planet's Star-Lord represents the EFFECTS, RESULTS and that Planet's Sub gives idea of the FINAL DIRECTION of that result.
