If you really actually learn all that, you can apply it easier to make your recordings sound perfect. I believe it came out either the mixing audio handbook or something very similar to that, being I have the book at home lol. Learn where your mixes should sit, and how they should sit, and if they don't, EQ them, compress them, delay etc till they fit right. In the end, the actual mix (commercial) would look something like what is shown on those pictures, unless you were deliberately trying a different thing.
