@Argulor: Yeah, no. Not quite. If you look at the title and the type of page this is (user blog) you can tell that it is a fan-made idea. While it is about fact it is divided and organized into whichever way the author feels. It would probably be mostly accurate though since Jacques never made eras specifically if could never be considered canon.
