Fine, the 5% reduction in opportunity is going to come from the aviation side of the house because SWO, SUB and SEAL/EOD are undermanned... that's going to translate into about a 10-15% reduction for pilot/NFO selection rates with a fairly decent chunk of the pilots getting picked up dropping their letters so ther can get out at the MSR which falls after the board (like previous years), so they'll pin and bail to a major airline of their choice leaving more slots open to pick up above zone next year.
Don't worry though, if you FOSx2 as a pilot you can leave the Navy on a Friday and be in indoc at your first company in your civilian flying career the following Monday (I've seen it happen).
