I get it, I mean I get the conundrum. Don't forget, the fitrep is supposed to be more of a prediction of future performance , not a report card of past performance. If you look at it like you have a DH who, out of all the DHs, would make the best skipper then that is something your community deserves, right? And if that person is most deserving, out of all the DHs (this is saying something slightly different) then the fitrep system doesn't provide a way to basically tell the board that "Hey board, guess what? I lucked out in my squadron and got TWO number one performers." So if the skipper gives that person a #2, then that person and your community both get shortchanged- think of it that way.
Soft breakouts notwithstanding and block 41 language like "read this carefully- reporting system constraints kept me from rating this person as number one, my strongest possible recommendation for number one except the system made me give him an MP, ooh rah press 100% now," let's not be naïve, your real number one is tucked away a couple blocks lower on the page. As it is, there are already a lot of commands with a number one and a number one-and-a-half performer in their summary groups, which is a lot of statistical anomalies. Coincidentally, 80% of everyone you meet is an above average driver...
None of this makes it "right" or fair if a person was truly a #1 performer but just isn't interested in the A-track. For the sake of fairness and people applying to this program, hopefully the process considers "number one-and-a-half" EP fitreps on equal footing to #1 EPs... but I doubt it. By golly, that would be logical.
