I wasn't suggesting that families would move, just that they would select lower-intensity schools that they currently have access to. For example, families in Menlo Park can send their kids to high school in Atherton, Redwood City, or San Carlos. If they can get an edge by sending their kid to a school in RWC, where they'll be at the top of the class, and apparently get a boost when colleges weight their SAT, I wouldn't be surprised if some families started choosing this path.
