Hope someone can help me answer this problem: NRMP recently decreased the number of rank order list slots to 300 from what used to be 700. From my understanding and what I've read, the most important thing in the couples match (if the priority is to match) is to make every permutation of every interview. So if both partners had 10 interviews each, that would make 11x11 (adding in the no match codes) = 121. If both partners had 17 interviews, they would be unable to make every permutation as 18x18=324. Is there a way around this, or did the NRMP just make it harder to successfully couples match?
