Fun question. I love strategic thinking.

This looks to me like a very weak and obvious attempt at disempowering “pushy” parents.

The most effective strategy might be for your children to be brutally honest while still respectful. The innocent desire of a child can perhaps be more powerful than anything you could have said.

You and your children could also perhaps turn this into a leadership game/practice when planning for the conference—less pressure if the focus is on the game and getting better each time.
