Can the ATP chart replace the Rasi chart in prediction?
The natal chart shows the entire life. But, if one uses a wrong or imperfect dasa system, it is easy to err in timing events. I am far more comfortable with ATP (annual Tithi Pravesha) charts as they are focussed on a one year period and are easier to judge. Whenever I have just a few minutes to spare and have to give a quick reading, I rely on ATP charts. And I am quite pleased with their reliability.
