There truly is no need for such tests Ira. The more you test, the more you'll realize this guide accurate on everything. I understand you are relatively new to this and that it can be hard to trust what others say without any proof or support, but sometimes you just need to trust what others say. The ones who contributed to this guide have a lot of experience and know what they're talking about. They have authority on the subject. There's a lot of knowledge to acquire in life overall, and if you put everything back into question, you'll be a slow learner. As an easy example, most people could not explain why we know (from simple observation) that the earth rotates around the sun, and no one has actually SEEN the earth rotate around the sun. Yet, everyone believes that the earth rotates around the sun. We trust the authorities in place on that subject, and you got to do the same thing with this guide.
