I have not participated in such a debate, and I think that generally, the flowsheet/notecard logic can be useful to prepare a single volley of argumentation at the preparative stage. For example, I want to discuss X in an article; I pull up my references (notecards) and sew them onto my own points, trying to include both pro and contra, and then send the document to a friend, with an understanding that he might outright condemn such organisation. The main thing seems to be the judge and not a debater when you evaluate your own work, and to judge consistency, fullness and conciseness.
