Just because a diagrammatic explanation has ended up on this page doesn't necessarily mean that some of them don't make points that are equally valid to most all of those on the other pages. It primarily means that I don't use them as reference points as how I do nearly all of the others; or else I decided not to concentrate on several of the different aspects which are mentioned in some of them. These do, however, tend to be more suspect. They are more preliminary in nature even though a few errors or changes may be found in some of those that appear on the other pages as well
