Formal board is an option but not one that is always granted. An unfit finding is. Navy wants to 100% keep people in. The PEBLO knows where you are at - either fit, unfit or a med board is in progress (even if one is not scheduled yet). My case is odd here I go:
Sep 17 Found fit
Requested look AGAIN
Oct 17 found fit (again -- no further action)
Dec 17 - Comnav pulled my fit status and I found out that QA is placing me in a med board
Mar 17 - found out about med board and completed med board - found fit (yet again).
Now I wait another 6 months to start this whole process over -- I leave the service in May of 2019... I can't re-enlist due to this new "12 months and out" policy that will be hitting each service in the coming months.
Fun times. Fun.
Just noticed last update was Mar 7 -- any news?
