The board has already taken place, so it really doesn't matter. #1 of 4 on a Frocking Eval is not really considered a breakout, and it definitely wouldn't be what separates you from other applicants who submitted an application.
Caveat: I don't sit selection boards, and the selection process varies depending on board members. Additionally, many other things factor in (e.g, experience in the field, accomplishments, leadership).
Unless it's a great degree of separation, such as 1 of 34, it may not make too much of a difference. This is what I've been told by a senior IWO who has sat a board. Again, many other things factor in, and you can still be selected if you were middle of the pack. It all depends on how the board views your application and credentials.
