Teams may modify and improve their devices to any extent they desire during the period between the Regional and National competitions.
This change represents a new approach to this competition. The Regional competitions are now to be viewed as the mechanism for determining the TEAM which did the best job in preparing for the Regional competition. The team is then free to prepare its "game plan" for winning the national competition.
The Student Design Contest Committee believes this approach will make for a more exciting (and often less frustrating) competition at the national level.
