I'm nowhere near that point (going to SERE, that is), but I can tell you based just on my time waiting around in A-pool, there are way too many variables to do that. I got here in mid September, expecting to start API in November or so. Initially I was told I'd start right before Thanksgiving, then I was told 05 December, then I was told right before Christmas, and most recently, 20 March. So no, there's no accurate way of guessing how long the pipeline will take you to negotiate. Don't bother trying to game the system - if it's even possible, it's not worth the effort. Cross your fingers and let the chips fall where they may....that's kind of a common theme throughout flight school and the Navy, I'm gathering.
