Not disagreeing Lumpy, but on the other hand I never got a good brief or was told what boards "Want to see" until I was a retread in Kingsville. I had 3 of 4 COs in HSL land who had been BUPERS guys as senior LTs/LCDRs, and not once do I remember an AOM/Training on "this is what is good, this is what is bad, and why".. Maybe a 4-5 minute part of the FITREP debrief if you were even there (for the non HSL familiar, your CO does not deploy, so if you are deployed during periodics, you get what your OIC fights for mostly)
CAPT Bulis, CAPT Finn and CDR Mundy (Bulis was VT-21 CO, but had been a 121 JO, Finn and Mundy were COs at 121 during my tour) all sat JOPA down, and described what is good, what is bad, and why. A bit of too little, too late for me, but they all did a great service for their JOs and DHs by actually going over the board feedbacks and such with the wardroom.
For the record, the only periodic #1 EP I had was written by a member of this board, and when I went to turn my self written FITREP in, he told me "it's taken care of". A prime example of a leader knowing his people, and knowing what the board needed to see. No fluff, no BS, because I had done enough to warrant a good FITREP with no filler.
