If they gave us 7,8,9 weeks, you lose a whole lot of the challenge. Sure things would be better, but not necessarily good for everyone. Basically what would happen is veteran teams and teams with tons of resources would get their robots perfect, while rookies wouldn't ever approach the samer level for the most part. Also, 6 weeks is a long time to be spending all your free time doing nothing but robotics. Im not sure many teachers and/or students would be sane after 9 weeks of building
Also, FIRST gets last priority during shipping with FedEx, since it is free, so they have to leave lots of time for shipping the bots.
