Do not speak too quickly as it does not allow me to fully grasp what you are saying. I understand that sometimes a lot of information needs to be shared, but not at the expense of understanding for those listening.

Pretend that I know nothing (but I do, I have a lot of judging experience) about your topic, which sometimes may be true, and explain what you think I may not know for clarity (i.e. abbreviations, acronyms, jargon, etc). Then convince me why your side should win.

To be completely honest I am very new to judging, and don't know all of the ins and outs of a debate round. This means that clarity makes a big difference in how I will vote if you are unclear on your argument.
