In addition to what Mr. Pockets (Nathan) said, we also kept our team members busy scouting. With barely enough scouts to keep our scouting service up and running, they were kept busy with constant scouting. Not the most ideal way to keep extra teammates out, but it worked.
It also helps when there's nothing to do in the pit. When the robot is working and there's nothing to fix (though we all know that that never happens
), watching matches is definitely more interesting than sitting in the pit doing nothing, so virtually nobody is there. Right after a match, however, our pit does tend to get a bit crowded with the drive team, strategy group, pit crew, and the occasional scout. After we assess whatever problems we may have, the drive and strategy teams usually leave, which leaves about 4 or 5 of us in the pit, which is a good number.
