I would like to ask for clarification on this. For example in the rectification video fro Muhammed Ali, if we didn't find 3 cusp related transits, could we look at 5 cusp transits before going for changing the time? Does 5 cusp work for top athletes or is it too secondary? Thank you
No, do not use bhavat bhavam for trigger transits.
Thank you. A related question since I mentioned Muhammed Ali above. If I wanted to rectify the chart of a pro tennis player, is following the same principles enough, namely the karaka of Ma for competition and 3cusp lords? Or should something be added?
Yes, same thing.
Generally plus or minus a day. BUt you can say, the time its in the same navamsa, so if the planet is in the 5th navamsa, when the transit is in the 5th navamsa, unless its a rasi aspect of course when 5th navamsa lines upto 4th navamsa. THe moon works a full 30 degrees berore and after.
