In Section 3.1.1 - 3.1.2 about Pit Crew size, it says the maximum number of people on the pit crew is 4, but then it also says that if any pit crew member is under 18, then there must be a supervising adult on the pit crew. My question is: Does the supervising adult count as one of the 4 members of the pit crew? Could we just have a supervising adult that didn't work on a robot, and just supervised, and then 4 student members on the pit crew?
