Nope. I was an 8-year commitment and was in zone two years ago. I do note that the aviation bloodbath at the O-4 board correlates nicely with SECNAV's direction to target 70 percent versus 80 percent. Note that the 11XX crowd has consistently been selecting at 80 percent plus. So naturally, to depress the overall average, the 13XX community is getting hosed. Why? Dunno.
Some 1310 communities (TACAIR) have had 8-year MSRs from winging for a while, but Rotary and MPRA was a relatively recent change. I remember when I applied for STA-21 in '03, it was a 6-year commitment, but when I finally selected aviation in Dec. '05, it was 8 years for all 1310s. Clearly, that would mean more LTs around for the O-4 board, whether or not they want to be. I'm stretching here, but it could also explain the O-4/DH pain in VFA, since they used to have a disproportionate number of LTs eligible for O-4, and now all of us helo and big-wing guys are jamming up the works (As I understand it, the O-4 board doesn't care what platform you fly, only that you're 1310).
Too many people rant about the selection rate (%), but that is barely one piece of the puzzle. Also, the selection rate shown on the far right of the board stats document is total selects divided by only the IZ eligible, so it can be above 100% (and is for some designators). I'm not sure why PERS thinks that number is meaningful, but you've got to check what is actually being shown. Ben4prez showed above that the total number selected hasn't really changed much.
Here's a graph of Ben4prez's numbers:
Yes, selection rate has taken a dive, but look at the rise in eligible IZ candidates and notice that the number of selectees has oscillated. The overall trend is down, but only by ~11% (321 from 359).
