If your multiple passes are taking longer check your purpose. Mind mapping helps train the mind to stay active while reading.
If you feel you need to start traditional reading check your question. What did you want answered> You're allowing yourself to fall into passive reading.
Remember to keep the activation passes short. Set a timer. It's easy to overrun and lose sight of the goal if you don't have something to remind you you've got to pull back and check where you are heading.
Like a plane flying to it's destination. You have to check frequently that you are on course. Leave it too long and you wind up making major detours.
