Yeah, this was IPZ. My record was clean - PT tests in the high 90's too. First thing that comes to mind is a 6- and 12-month deployment bookended by mild or weak Senior Rater push lines. Beyond that, it's an admin fail or ..just.. anyone's guess.
There was another comment about positioning non-selects for the APZ board. I'm laughing, because -in this case- I've been TDY en-route to PCS for the last three months. If I had a chance to be in anyone's top XX%, that ship has sailed.
Offer still stands - selects and pass-overs get a round on me!
