At any campus, the overwhelming majority of PNMs who end up bidless are ones who take themselves out of the game, usually because they are unhappy with their remaining choices.

Sure, some PNMs will get released from all chapters; although it is impossible to know why a PNM was cross-released, the following factors do not bode well: low GPA, bad reputation, junior/senior class standing (juniors fare better at some schools than others), unkempt appearance, very poor conversation skills, or not having recs at schools where they are important. At my alma mater, 400-500 PNMs go through (and increasing), and I know for a fact only 11 were cross-released in 2006.

My campus does guarantee a bid to any PNM who makes it to preference, maximizes her choices throughout and ranks all of her preference chapters. Not every school has a guaranteed matching policy, but the more chapters a PNM ranks, the higher chance she has of being matched.
