For a small fee, I will go to your enemy's conference presentation, be the first one to raise my hand, and have "more a comment than a question" for 3/4 of whatever time is allotted for questions. For a bit extra, Ill make sure to remind them of how tenuous their argument is.
My buddy is a professor at a private school that has a 8-1 ratio of student to faculty. They actually have something similar to your scenario baked into their masters and doctoral programs. Every student gets a faculty member assigned to them that helps them through the program, and during student presentations they'll throw them softball questions tailored to the work they helped them put together.
