Depends on your mind probing questions. If you are just activating with no real curiosity or questions to find answers you have nothing to connect understanding with.
Also expect to do more passes if the text is for you normally a difficult one to consciously comprehend. With each activation pass you build the knowledge and understanding.
Another point if text is difficult to activate, mind map. it helps you to build and see the building of your comprehension with each activation pass.
