Getting to the camp is what all federal inmates strive for - it's the easiest time to do in the BOP. All federal inmates follow the same guidelines for release. Good time is 15% of the sentence that is granted to the inmate when they report - all they can do is lose good time, they can't gain more good time. Their release date reflects doing 85% of the sentence. RDAP is the only real way to get an earlier release than the whole 85%. Inmates that graduate from RDAP earn up to twelve months off their sentence plus at least six months of halfway house.
