It is my opinion that PI has a universal type of *none, which can adapt to your environment. How you present yourself and the way you are perceived as a result of your presentation is very important. I know this because I\'ve made KR#1 work for me (contains a hefty amount of PI in it.) in a professional environment, such as school and work. Just my personal experience.

I have only tried PI and NPA, and RM is on it\'s way. As for my personal results: out of NPA and PI, PI significantly out-performed NPA.
