Honestly, no one here can give you the answer to this. It depends on when the MOC submitted his/her slate, whether or not there was a principal nominee, how many are on the slate, how many are triple Q'ed, etc.
Obviously, an MOC who submitted a slate with a principal nominee in November and that principal nominee was 3Q'ed in November . . . my guess is that's a done deal and the other 9 (fewer if others had an LOA) are in the National Pool.
However, if an MOC submitted a competitive slate on Jan. 31 and there were no LOA candidates, and some of the candidates finished their packets in late January . . . that slate might well still be under review.
The bottom line remains that USNA does its very best to notify all candidates by April 15 whether they are accepted, waitlisted or turned down. Until then, there isn't a whole lot of rhyme or reason discernible to folks not at USNA Admissions as to why some get notified earlier than others. To be clear, I am sure there is a well-thought out process for reviewing records and offering appointments -- just that it isn't promulgated to candidates or BGOs. And, honestly I'm not sure we really need to understand the nuts and bolts.
