I would sleep. (: Just kidding... no one sleeps during build season. I would probably put a little bit more time into every part of the process- they are all very important to a final outcome. I would say the thing that always gets pushed aside for too long is the code, so a longer build season would make sure that gets the attention that it deserves. More driver practice would also be great. And yeah... now that I think about it, sleeping sounds great.
I like the fact that there are only six weeks, though. It forces us to be creative and to use our time wisely. It also mirrors "real-world" engineering projects where deadlines are very important.
