I got out after my initial obligation. After getting my SWO pin, I knew my choices were to either, (1) bounce and use the GI Bill on law school (thanks BDCP!) or (2) apply for the law education program. While certainly not the main reason for my choice, the extra BDCP years actually discouraged me from staying Navy for two reasons.
First, LEP tacks on 6 years of obliserve. With my BDCP years, that'd push me to about 12 years AD. So the weight of the decision was heavier--I knew I was really deciding whether or not I'd be making the Navy my career. I knew I wouldn't voluntarily leave with less than 8 years to the pension.
Second, LEP eligibility is limited to JOs with "2 to 6 years' AD service (including any active enlisted time) as of the time of proposed entry into law school." Thanks to BDCP, I had 5.5 years of active duty service when I finished my 2 sea tours. So I knew it would be an extremely tight window and I really needed to be motivated enough to start the process during my 2nd sea tour. After a crazy OPTEMPO in my first tour, I wasn't gunning to sign up for the full 20 years ASAP.
That said, I still think BDCP has a generally positive impact on retention. It definitely impacted my decision to go Navy over other branches. I figured that as a civilian applicant, my personal "ranking" of branches was imperfect because I didn't have enough direct knowledge of life in different branches. So I figured I would follow the $ and apply to whoever offered college $ for students w/non-tech majors. Well...I did know not to apply Army
