Yeah going over a few prompts and brainstorming for a few minutes about how you'd organise your thoughts is the best way to do it. Much like with LG its more important to get a good "setup" down and then write with a plan.
While I agree its unimportant in comparison to the scored sections, I just took a Kaplan workshop on writing section strategy and they made a good point, that if it was seen as so uninportant, they wouldn't have added a whole new prompt and added 5 minutes to the section. Obviously, someone considers it important, or else they wouldn't bother making changes. It is one of the first things seen in your application file. But as long as they see you can organize your thoughts coherently, you'll be fine though.
