Originally, the release of all results was set up so that TRIAD could congratulation their troops and pat them on the back. Then the public NAVADMIN would be release supposedly (and exactly) 24 hrs. later.
It came to pass that after the TRIAD release, not all selectees, or those who made it, would get notified. Those on leave, those in another UIC, and a lot, and I mean a lot of Reservist were the biggest victims. That's why the public release became very important.
I'll also add that in the Reserve, it's also a matter of the CO, XO or CMC simply not giving a damn. This is from my direct communication with some Reservist.
You'd think that at this point it would be a "lessons learned" to get the public NAVADMIN out on time but I guess not. This is the third time I have seen this happen and all three are very recent. Shame on the Navy.
