While I wouldn't use that material directly ever again, I noticed that I would often paraphrase a paraphrase, so to speak, because I would remember some of the material.
Tangentially, this thread shows that people prefer different ways of taking (or not taking notes) usually due to a habit itselfc as opposed to superiority of one method over the other. It reminds me of Dvorak vs qwerty, while technically superior for typing in English, the cost of switching is not worth it for most people out there.
