Win the flow. As long as I understand you (read: no spreading), I couldn’t care less about how you speak.
My full paradigm is a little long so I've written up a summary of my preferences below.
1) Weigh all of your arguments. Odds are, both debaters will be winning arguments by the end of the round, so make sure to tell me why the ones that you’re winning are the most important. Also explain why your weighing mechanism (probability, magnitude, etc.) is the best one.
2) I place a lot of work on framework. If you provide a weighing mechanism at the top of your case, and actually engage in the framework debate, I will be very happy and more likely to vote for you.
3) If you're the second second speaker, you can spend four minutes on your opponents' case. Both first speakers may spend two minutes on their side of the flow in summary. All arguments that I may consider must be brought up in final focus.
4) I always prefer going down the flow line-by-line in summary, rather than randomly-numbered voting issues. Do whatever you want in final focus, but make it clear which arguments you're talking about. Whichever strategy you choose, SIGNPOST.
1) You need to weigh arguments. I think of weighing as really important in LD, but in PF, where a consequentialist framework is almost always accepted on face, weighing is absolutely necessary. I don’t want to intervene, but I’ll have to if no one is telling me what specifically I should be voting on, and why those issues are the most important. If you rely on a standard weighing mechanism (probability, magnitude, etc.) I expect you to tell me why that weighing mechanism is better than others.
2) Since my background is primarily LD, I place more weight on framework than most PF judges. Framing the round to provide a weighting mechanism that benefits your arguments is extremely helpful, especially if your opponent doesn’t have a framework at all (this strategy won me quite a few PF rounds). I do default to utilitarian cost-benefit analysis, but I will evaluate the framework debate before the contention-level debate if one is presented in the round, and I am more likely to view the round as a whole in a positive light (read: higher speaks) if there is some sort of framework debate going on.
3) In rebuttal, I don't think the second second speaker has an obligation to respond to their opponents' rebuttal, so they can spend all four minutes attaching their opponents' case. Similarly, since summary is primarily for extending offense, it's okay if both first speakers spend the entire time on their side of the flow. Neither of these are mandatory - do what works for you. In final focus, I expect all arguments you want me to consider to be brought up.
4) In summary, I’d prefer you go down the flow and emphasize important issues by telling me that they’re important (and why), rather than giving randomly-ordered numbered voting issues. You can give voting issues if you want, and I will try to find them on the flow, but you have to remember to SIGNPOST. In final focus, I don't really care what you do as long as it's very clear which arguments you're talking about (that often means referencing contention numbers/subpoints). I don't you to risk me missing one of your arguments, so SIGNPOST. (Did I mention SIGNPOST?)
