Unless you are the #1 guy and on the the Commodores it's all a game of chance. Even then nothing is set in stone.
Says the... oh nevermind
And WRT the "policies" of what you put down on the selection sheet, I may have had an inadvertent hand in that. I was encouraged by my Navy StuCon-O to put down anything I had pressing on my selection sheet. I was trying to get West (preferably for the FRS, too) so I could be close to my for-two-more-weeks-fiancee, who was, in a similar situation, contractually obliged to work in SoCal. Under his advice, I put that info down on the sheet. When I got HSL-W (via Mayport), I went in and talked to
my StuCon-O to see if there was anything else I could do, seeing as he was very optimistic prior to selection about me being able to get out there. I was obviously not happy about not getting the spot, but I wasn't crying foul or unfair.
Later that week, the Marine StuCon-O, who must've been in the room while I had the talk w/ my StuCon-O, decided to use in an all-students meeting very very specific excerpts from my situation while impressing the fact that it doesn't mean shit unless your spouse is mil. I have private opinions on the professionalism of publicizing specific personal stories of those in your purview to make a point.
Here's how "Quality Spread" was explained to me. Amongst the folks who wanted the two West Coast spots, I was second-ranked. 1st got it, obviously, and someone other than me got the other one.
To sum up my quality spread experience: I was not happy and wasn't going to lie about it. Did it make things more difficult for me & Mrs Beans? Oh hell yeah. Like everyone else (except for the rare few who DOR upon not getting what they want), we got over it.
And don't buy a house to force yourself somewhere. That's only worked for those in the FRS who are already selected to go to this-or-that duty station, and the house ownership
tends to keep them from losing that preassigned duty station.
