Topical CP s are fine. Competition is the key. No delay CP s or permutations. As I have gotten older I have become more confident that it is usually the debaters who are unclear rather than me who is unable to understand. I will not pretend to flow arguments and then fill in the gaps at the end of the debate by calling for all of your evidence.
Debate is an oral activity.
Be clear in both the tags and the evidence. I can handle speed as long as you are clear. I tend to read a small amount of evidence at the end of a debate. I will read evidence from arguments emphasized by the debaters or on arguments that both sides did not resolve. Cross-examination should be useful.
