I worried to much with the tangerine technique when I first started. I wouldn't worry about it too much. It's just there to help you concentrate your mind. So, that you don't stare through the page and not read anything. I used to do that alot. Now I just think of it as a fixed point above my head and then I'm ready to go. The best way to get good at PRing is just to use it on everything. Use any of the techniques anytime you get a chance. Hope that helps.
