The new rankings won't change the fact that there will be PNMs that do not have a full schedule for each round. Chapters can't be forced to invite back a PNM (with one campus as an exception), so there are no guarantees that PNMs will "attend the max number of parties". All it means is that PNMs must attend all parties for which they have invites and space in their schedule. It means that just because a PNM put a chapter in her bottom X number of chapters, she still may have to return for the next round depending on how many invites she gets.

Attending the max number of chapters on pref has nothing to do with anything. SOME Campus Panhellenics have a "guaranteed matching" policy. If a PNM has attends all of the chapters' parties for which she was invited and had room in her schedule throughout recruitment, has at least one chapter remaining for preference, AND ranks ALL of her preference chapters, she is guaranteed a match to one of those chapters. I'll emphasize that not all campuses have this policy. Even at campuses that don't have a guaranteed matching policy, it is pretty rare to rank all of your preference choices and go bidless, but still a possibilty.

There is no way to guarantee a bid (except at Tufts) because a Campus Panhellenic can not guarantee that a PNM won't be released by all chapters.
