Well "brain", never expect the S/A experience so much, you probaly have heard of: the more you expect, the more you fail, so whats the point,

if you just use the system like 2nd nature, then one day, you will have it, I mean you will notice it.( without thinking S/A all the time). 5-10 books a days will be a good way, but not everyone have that amount of time, I nearly gone mad when I PR 5 lecture text book a day (more than 5000page), so use the system when you read, I.E, PR the book, paper what ever before you start reading even you don't want to use the full system at all. But of course I will pefer you use the system fully.
