I was an active competitor in HS and college. I currently coach Newport HS.
I do have my Ph.D. in Composition and Rhetoric, so I can follow your logic, and if you choose theory, I have a VERY high bar.
As far as spreading, I do not like it. I have a hearing impairment - and this online environment and spreading can make following you difficult. I can only judge what I am able to hear. I will ask you to slow down if it is too fast or unclear the first time. If you start "super spreading" I will not give you more than 27 speaker points, because the speed truly detracts from the art of speaking.
Make sure to stay respectful to your competitor, as well as me. Disrespectful words or attitudes will result in a lower score.
I like arguments that have a clear value asserted and pursued. The more sign-posting and off-clock road maps the better. Also, I love to hear the voters at the end.
I am open to many types of arguments - but make sure you let me what criteria to judge the round - and how you fulfilled it. That is your responsibility as a debater- not mine as a judge.
