What a neat idea! I like that your audience for the presentation are in the EC style.
I didn't realize before the presentation that you are "judged" on your pace. I was told I rushed the beginning and middle. Since I was only told in the practice not to go over the time limit, I didn't realize that my overall pace could be too fast. Of course, in real life you need to pace yourself, but it might be a good idea to let the player know it's a feature of the game too during the practice.
