A rough example: Person A holds spots at School A and School B, and decides to choose School A instead of B, so a spot at School B frees up. That spot is then occupied by Person B off School B's wait list, but he already had a spot at School C (I think this is correct). Anyways, what occurs is a cascade effect across schools, and one school in the cascade will be TCOM. What is interesting is that you could have a person, Person Alpha who is waitlisted at TCOM but accepted to DO School 2, and Person Beta, who is waitlisted at DO School 2 but accepted to TCOM. Say a spot opens up at TCOM and Alpha gets it, then he could potentially free up a spot for Person Beta at School 2, which leaves another spot for TCOM.
