BTW, since I have been here I have seen this question about when to show up. I gave the pat answer to show up as late as possible. Here is another way to think about it...
** Note: When I went through AOCS the DOR rate was >50% some class started with 30-50 and ended up with 7, one class had like 5. So I suspect (again based on what folks here are saying) that this insight will apply EVEN more in today's OCS
If you are a the kind of person who will make it through OCS, do well and fly for the Navy, it should not matter when you show up, the first days are just noise. Someone who can't get through the first 48 hours would not make it through the program no matter when they showed up and someone who is committed, prepared, and gets through the program will make it through no matter when they show up. So in the end show up whenever, commit to the mission at hand, kick some ass, and come out the other side smiling (understanding that when you showed up such a small deal you laugh)...
My two cents. In any case good luck to all. Godspeed and kick some ass.
