Andreas,
I am glad that you are doing that experiment. I recently experienced spontaneous activation while taking few comptia exams on A+, Server+, Network+ and working on the Security+ now. A lot of time, I followed my intuition and the answer for each questions during these exams where just popping out before I even finished reading the questions. A lot of time when I did not have a clue about a question, the answer just popp up on the screen out of all the choices. But it required to stay in that ideal state where evrything is just flowing. I did not second guess myself or change my answer to avoid creating any doubt about what was happening. Sponteneous Activation often happened to me when I kept myself relax and did not doubt what was happening. I could not keep that state all the time but most of the time. I did not spend a lot of time studying but just wanted to see how photoReading was working for me. I passed all the exams on first trial. My goal was just to have a passing grades for these exams and not spent a lot of time reviewing and studying these courses. And I got the result. I am sure if my goal was to get a top grade, the power of my intention would have provided that result.
As you are doing your experiment, we know that the result will change between subject ( people doing the experiment ) because of several factors such as motivation, purpose, ... I am working on my CCIE and I would like to join your experiment and share my result too. This way we all can share what work and did not work individually, how much time and what technics or strategy used. I will be glad to share that with you. Right now, I only have a couple ebooks on the CCIE subject and I will appreciate if I can access your FTP site to download some of yours to perform the same experiment as you. I am looking forward to your response.
