This is a hierarchical system. Dash or indented outlining is usually best except for some science classes such as physics or math.
Best Use: The outline format can be used if the lecture is presented in outline organization. This may be either deductive (regular outline) in which the major points are refined by minor points or inductive (reverse outline where minor points start building to a major point). Use this format when there is enough time in the lecture to think about and make organization decisions when they are needed. This format can be most effective when your note taking skills are super sharp and you can handle the outlining regardless of the note taking situation.
