Finer Divisions
Tajaka annual chart is basically the commencement chart of mahadasas as per Sudarsana Chakra dasa. Tajaka monthly chart is basically the commencement chart of antardasas as per Sudarsana Chakra dasa. Tajaka 60-hour chart is basically the commencement chart of pratyantardasas as per Sudarsana Chakra dasa. By going to finer levels, we get 5-hour charts 25-minute charts and 2-min-5-sec charts. Each chart shows how the corresponding period will be.
Judgment of charts
Strength of the lord of the relevant houses and sahamas and Tajaka yogas involving them should be seen. Placement of planets eith respect to muntha is also important. Muntha is the dasa/antardasa/pratyantardasa/whatever sign with respect to Sudarsana Chakra dasa. Suppose someone has Virgo lagna. In his 26th year, Libra dasa will be running and so muntha is Libra. If his natal chart has Venus (lord of Libra) in Taurus, then antardasas in Libra dasa go as Taurus, Gemini, Cancer and so on. If we are looking at the 4th month in the 26th year, Leo is the antaradasa sign and becomes muntha in the monthly chart. And so on.
Pancha vargeeya bala, Dwadasa vargeeya bala and Harsha bala of planets should be seen and lord of the year and lord of the month also matter.
