It all dependents on what you are looking for. It is true that DIP does not related to college admission directly for a 7th grader. In fact no other summer camp does that. However, the 400 points difference in the results of SAT test does tell how strong his/her curiousity is in terms of learning new things. My kid got a free ride for the DIP and met several talented peers during the summer camp who already won national intellectual awards. They still keep in touch.
It is just my opinion.
