It's a question of opportunity cost: would the quality of engineering outreach that a team would achieve by not attending another FIRST regional be better than the quality of engineering outreach the team is recieving at attending another regional?

From there, you need to define quality matrices (Percentage of students enrolling in engineering higher ed programs? Finishing engineering higher ed programs? Taking a job in science or technology-related fields? Enrollment/Demand for science and technology-based classes? Higher math standardized test scores?), and figure it out mathematically from there. I would definitely be interested in seeing the data on that.

But in the end....I don't mind teams going to more than one regional. Just a personal preference.
