Rahu query - concrete charts analysis

I think you may also have  said that it's a momentary success, president Emmanuel Macron was elected during his Rahu first antardasa. It seems like the success was short lived for him with the situation he is currently in. I also have a friend with rahu in the 10th, and it seems it was indeed only a momentary success though it's not always easy to judge. 

Yes, that's how it works, it gives success in rahu rahu and then the  rest of the dasa is mediocre. That's the example I used in Gore's chart and why he never won the presidency.
