I believe the saying "The more the merrier" applies everywhere but in the pits.
2 people should be the minimum so you have a safe lift team for your robot, and maybe 5-6 should be your maximum.
I'll admit my team has a problem with this being rather large, and with most people interested in knowing what's up with the robot (especially after matches where the robot has taken a beating). Everyone wants to rush back to the pits after matches like that, and ask the pit crew what's happened.
Note that as a Safety Advisor I'll be looking for this among other things in Philadelphia this year.
Just keep it safe no matter how many people are there, but keep a fair limit.
Your team's pit area isn't a Volkswagen or a Phone booth folks..
Let's not try to set records as to how many people we can fit in there.
