To answer your question, the SA learns before you will. Since our DS did not apply to USNA, I do not know what their website for candidates looks like. For the AFA it has a subtitle that shows your nom sources that you received and dates.
For our DS, one MOC showed up on his AFA login 4 months before we received the letter. No lie...cut off date was 10/1, it showed up in Dec. on the website, the letter arrived in Feb, postmarked Jan. 31st
Actually, every nom for him, showed up before the letter from the MOC in the mailbox. One by a few days, one by weeks, one by months. DO not take the leap that one MOC is going to operate like the others.
Typically, if the MOC places the list on his site it is after the letters have gone out. SO for marciemi, that would make sense since it gives @ 5 weeks between meeting and the public announcement, allowing week 3 or 4 for private notification.
Your MOC may not want to release that info so they are not inundated by candidates...think about a state like VA with 350 applicants for the 4 branches that they whittled down to 75-80. If they stated the week or date, they would spend that time answering phone calls instead of contacting each branch, sending out notifications to candidates and placing public press releases. (Did you notice that some MOCS ask if you want it printed in your local paper...guess who is in charge of that...not you!)
