At thi time Roman is correct.
The SA's start out with @9K pcqs, from there it is whittled down to about 5500-6000 qualified to open a file (candidate). After that it gets whittled down again, some will not get noms, some will not be medically qaul or academic qual, which brings you down to about 2100 who are triple qual with a nom in hand. People tend to calculate how many noms are out there and forget to realize some of these kids could have 5 noms (3 MOC, Pres, ROTC) not counting the VEEP. SO even though there are thousands of noms, the number of candidates that have noms does not necessarily equate to being the same number available.
