I agree. I was selected on last year's board and I've had a few friends tell me they know guys with "better" packages than mine not get selected. Better in their minds were higher scores and PPLs. I told them I'm sure those help but scores aren't everything. Maybe I had better bullets, a better personal letter, or a better LoR. I was doing things that affected every Air Force MQ-9 but my peers seemed to think the scores mattered most. I was 5/6 in my wing and 3/3 in the squadron (I had been there the least amount of time) and I still got picked up even though our #1 strat for the wing didn't.
Point of this isn't to brag but to say focusing on the job and really making those big impacts with your job or leadership really affect your board scores and ranking.
