Ah i see what you mean when you say “Jupiter is in the 9th bhava” , you are right, based on moon lagna, indeed jupiter is in the 9th house.
IMHO, as i a beginner i only follow lagna kundli and gochar. Trying to map the events. I have never followed chandra (moon) kundli.
I also saw during the events of my life lagna kundli came very close to predicitions when trying to connect dots looking backwards
