brp, photoread4me and AlexK have mentioned your purpose. It should be a strong and inspiring one. You can search the forum for lots of thread on purpose.
As to having 20 to 50 questions per chapter. I would suggest that you pick only 3 questions per activation pass. Then use the system and see what happens. NOPS it. If you try and force an answer you will not get it. You have to be relaxed and open to the experience. Don't go into it with expectations of how it is going to work.
Expectations of How things will happen is not the mindset of the beginner. Just because your used to How things happen using your old system don't expect it to happen the same way with this system.
That's why the time limit is tough. It has a need to learn x amount per hour. Anything less will result in anxiety.
AlexK would also say something like, "Don't try and learn two things at the same time. You don't know if you aren't learning the PRWMS or not learning the material your using system on."
I'll end by suggesting you try with a good strong purpose and only a few questions. The forum has several good threads on creating good purposes and questions.
I wish you the best of luck.
You are perfection.
