I did high school debate for 3 years. I did nearly every form of debate except LD. I have qualified for nationals twice and broke at the NFL tournament. I also was a City Councilman. I am by no means a lay judge, however I believe debates are won on the merits of the arguments. Evidence and facts matter. I have done and judges most forms of the debate.
Treat your opponent with respect, you will not win any points from me by belittling them.
As far as speed goes, I'd say if your max speed is 100 miles per hour, go 60 miles per hour for me, I want to flow your arguments and if you rush them I may not get them all. Quality over quantity.
Do not drop your contentions, or your opponents, I will flow them as dropped and they can decide the ballot for me.
I am not very familiar with the K but open to hearing a K case and can and will vote on it if the case is made.
The flow is important, do not drop contentions or arguments or I will flow to your opponent as a drop and a won argument. Give me voting issues.
Enjoy your time debating, its about learning, not winning.
