Before I answer your question, please make sure not to insult any planet, otherwise you will start seeing negative results within just a few days. In this scenario, within 11 days some kind of problem with finances/expenses and anxiety due to it will arise somehow.

It can be any planet, Saturn, Mars, Rahu, Ketu; Whatever good or bad they are doing is totally based on the karam of you and your lineage. So instead of Insulting any planet please give five minutes of your time, and thank them daily after waking up for whatever they have given. Within some time you will see the problems from your life slowly disappearing automatically.

Now coming back to your question, to know what kind of results Rahu is giving, check what happened in the shookshma or prana dasha of Rahu each time you went through it.
Also if you get sudden results such as sudden ideas/job offers/solutions to problems , then you know that Rahu is good in your chart.

If you see negative results are occurring, then start chanting Durga Shaptasati path daily after waking up and pray to Ma Saraswati. This will give you relief.
