Ive noticed the same thing. not just with azb, but with reading other types of instruction. My head gets jumbled with so much info i find it hard to focus. What I started doing awhile ago is write down all the things i've learned in a notebook. then when I practice, I only work on one thing from my book, and cross it off at the end of my session. during tournaments, I just forget all that stuff and let my muscle memory do the work for me.
