There has been a small amount of discussion about this in the global FLL forum. See http://forums.usfirst.org/showthread.php?t=17889 The word in the forum is that making sure that the slide is properly attached to the center wall helps a lot. I will note that the sets used in the VA/DC FLL tournaments all start out new at the beginning of November, so they might not have as much wear and tear as the kits that your teams will be practicing with before the tournament. Unfortunately, I am not prepared right now to make a ruling on what the "expected" behavior for the rat on the slide is. All the ones that I have assembled slide really well when new, but none have them have been attached to an FLL table, or have had dozens of trips down the slide. Figuring out the "expected" behavior is important. If rats sticking is common, then it's expected and there is nothing that the referee needs to do. On the other hand, if a mission model is obviously doing something very unexpected, then the referee might think that there was a problem with the mission model and apply Benefit of the Doubt, which might include awarding the team the points associated with the malfunctioning model.
