Why two kundli reports can disagree
A kundli report is not one calculation. It is a chain: recorded inputs become planetary positions; positions are interpreted under a named method; tables assign points or categories; exceptions may then alter the outcome. Two reports can agree at one link and diverge at the next. Comparing only the final score hides where that happened.
The diagnostic above does not upload or parse either report. It turns visible classes of difference into an audit order. That is deliberately narrower than declaring a cause: without the underlying inputs, settings and rule output, software cannot know which report is correct.
The comparison order matters
1. Inputs before methods
Check the printed date, local clock time, place and bride/groom order first. If those differ, the reports are not evaluating the same case. Even a typographical AM/PM error can move the ascendant and every house-based reading.
2. Positions before interpretations
If the Moon or ascendant degrees differ despite identical printed inputs, compare ayanamsa and historical time-zone handling. An interpretation dispute starts after the positions agree; a settings dispute starts before it.
3. Named methods and tables
Ashtakoota and South Indian porutham systems do not contain the same tests. Even within an eight-koota score, published tables can assign different points. The useful evidence is the per-test row and convention name, not the total in isolation. The longer why astrologers disagree article explains those axes; this page is the checklist for applying them to two reports.
4. Dosha definitions and cancellations
Manglik practice varies by counted houses and reference points. Cancellation practice varies by source and school. One report can therefore detect the same placement and then set it aside, while another retains it. Ask for the rule ID or cited condition so an exception is a checkable step rather than a reassuring sentence.
What a useful report comparison contains
- the exact inputs and directional roles used by both reports;
- ayanamsa, time-zone handling and the key computed degrees;
- the regional method and each included test;
- per-test points, table names and directional counting;
- every cancellation, veto or restored point with its source.
Once those rows are aligned, the first difference is usually visible. If a provider will supply only a score and a verdict, use the questions in how to ask for the reasoning. A result that cannot expose its inputs, rule and source cannot be meaningfully compared.
