The tablet rendering was done by Dave Mucci with the Indian build. That build was extremely challenging to do any drastic customization in 3 days, since virtually no aftermarket parts existed (show was filmed months after Indian released the bike), plus fuel injection; plus electronics you can't simply remove without hacking the electronics components AND the frame is kinda fugly. The producers led the contestants to believe they would be working on older donor bikes.
I think an extra day would allow for more adventurous fabrication, more time to get parts shipped, better paint and more time to get things dialed in (like that jockey shifter). I agree that an extra pair of hands might get in the way.
I do like the Dirtbag Challenge
http://thedirtbagchallenge.com/info/1. One month build time
2. One thousand dollar budget (includes the price of the donor bike, all parts, and all work)
3. One hundred miles (on the morning of the show, meet up with the other Dirtbags and ride at least one hundred miles over every type of road WITHOUT a chase vehicle)
4. No Harleys
