Almost all of the discussion regarding ranking is about ranking advanced or categorical programs on the primary list. Very little information is available regarding ranking prelim programs at the end of on primary and/or on the supplementary list. Also, from ranking algorithm standpoint, A. Does the order in which the applicants are processed have any impact on the match? if so, does it put you at a disadvantage to have supplementary lists? B. If all the top programs are going after the same candidates and all top candidates are going after the same top programs, what effect would this have on the match? C. If the top candidates are going after regional programs, what impact would this have on the match? D. Is the algorithm and the software stable enough so that it would yield the same result if run multiple times? E. Does it really favor applicants over programs? If so how?
