It's not that people don't get it, it's that information is not available. For AD, no instruction states that SWO cannot be a third choice or should not be a third choice if trying to be considered for that designator. As far as the threads on this site, I am sure I can find information about that topic now but how is that any good. I didn't know about this site until a few months ago so forgive me if I am asking questions that have been answered before.
It's all a part of doing your research before applying. They're not going to put that in the instruction because it's just a board preference that is subject to change.
If there's not ond I already missed, I think creating a pinned thread that annotates current trends for the biggest designatorswould be beneficial in situations like this. I'm sure folks would still miss it and ask the same questions, but it would definitely make linking to information a lot easier. Lord knows, nobody wants to go dig through the September board thread's 150 pages for ANYTHING lol. Still, folks gotta make good use of the search option to review past board threads for pertinent information.
Question for you though: how were you picked up for the September IDC Board, medically TNPQ, and not given the opportunity to provide additional documentation and information for a waiver?
