In reality, the guidelines that they give out for the business plan is just a list of info that is necessary to include. I should know, last year, I pioneered (FRC Team 1625) Winnovation's business plan. We took it to the Lake Superior Regional in Duluth, Minnesota, and as stated in the records for that regional, we didn't win. Team 1816, the Green Machine did. I got to look at their business plan (which they have posted on their website), and I was completely blown away. Their business plan was some 20 pages, and quite detailed.
I'm currently making major revisions for Winnovation's 2013 business plan, working off of Green Machine's and Team 234 Cyber Blue Robotics' past business plans.
The bottom line that I've inferred is that the business plan should be somewhat extensive and detailed, though allowing for some info to be excluded with the assumption that the judges would already know the info that would be excluded.

Hope this helps!
