In our team, we have 3 groups that have priority access to our pit.
- Drive Team
- Pit Crew
- Chairman's Team
So in total, we would have a maximum of 10-15 people in our pit at one time. In Hawaii, multiple team members spent the majority of their time away from our pit, helping either of the Chinese teams, or LAN Down Under (4774), only returning to our pit when in need of tools.
Whenever we had people congregating in or around our pit, we would send them away back to the stands, or over to the other Chinese pit (4831 didn't get their visa's approved, so they had an empty pit

).
I did find this year that people were quite good at sensing that they were "in the way," especially after a match. I felt it a few times, and when people felt this, they were quite good at getting out of the way. This is probably one of the things that I think is quite is important to stress to your team members.
