This was the game I had to experience during my first ever official LSAT. It was awful. But after reviewing the game when the exam was released, I realized it was actually much much easier than I thought.
So I am going to say no unless your PT scores have been higher, on average, than a 161. If you are, on average, scoring over 161, then why not take a fourth time.
Basically say that you were scoring higher in practice and felt like your official scores up until your latest were not representative of your abilities.
Actively reading. Understanding and dissecting what you're reading rather than just absorbing it pointlessly. For RC I think you need to go back to the syllabus and work on re-learning low-resolution summaries.
