I can't speak to how far you can go to accelerate the process. However, I can confirm that PhotoReading 3-4 books/day and activating 1-2/week resulted in a big improvement in my skills. Why should PhotoReading be any different than any other skill I want to learn? I struggled with finding enough books for several weeks before it dawned on me that I could PhotoRead the same books multiple times. DUH!
