Sixteen divisional charts, Vimshottari to three levels, Ashtakavarga, Shadbala, Jaimini, Varshaphal and a reading of each area of life in plain English.
Dates of things that have already happened to you. They are not used to change your birth time — they are used to calibrate the forecast: the reading works out which parts of the classical timing rule actually fired in your life, re-weights them, and learns how strong a period has to be before things really move for you.
Three or more makes a difference. Leave it empty and the reading uses the textbook weighting instead.
The more you give, the sharper the result. Four is the minimum worth running; eight or more is where it becomes reliable. Hard, dated events work best.
