That is a rumor that will never come to fruition. There has not been parole in the federal system for over 25 years and it's not coming back anytime soon with the current administration. Incarceration is big business and it makes big money. Every year that i was in the federal system, there were rumors of how they were going to offer early release to first-time, non-violent offenders because of "overcrowding" or other reasons. None of them came close.

The BOP release date is accurate. Once the inmate gets approved for RDAP, it will change the release date. It takes about 2-3 months for the change to appear on their website. The good time credit of 15% is included in the release date and as long as the inmate steers clear of incident reports, that amount will stay with them to the door.  On 78 months, with good time there are 66.3 months to serve. If they get

Come on!! Ten days!!!  ...and you want to know if he can get out sooner?!?!?! Nooooooo way LOL

This will depend on his previous criminal history and his behavior while serving this sentence. The short sentence also is another component that is weighed in the decision-making process. If he gets to his counselor and continues to push the paperwork, he will have a better chance of attaining early release. 

Not usually, unless there is some perk at the county jail where he is

If he got a reduction from 6 years to 1, why would you think he'd do less that the reduced amount??? He's lucky as hell

Inmates don’t usually serve the entire sentence handed down by a court. Most can and do have their time shortened by as much as a third. Of those released last year and eligible for that 33 percent time off, more than 59 percent received the full reduction. At least 29 states offer “good time” for following the rules, which is granted when the inmate reports (that is 15%).  And at least 31 states offer “earned time” for attending classes, treatment, work

Yes, absolutely! You are credited for every day you are incarcerated against any imposed or pending sentence, no matter the location. If they arraign you, book you, and release you same day, that counts towards one day of incarceration.

Prop 57 releases must go through an application process and get approval. There are no "automatic releases" from Prop 57. The inmate must go to their counselor and ask if they are eligible. If they are eligible, the counselor knows the forms to submit. The process takes weeks.

All inmates start with good time credits regardless of the sentence. It is a built-in incentive to behave.
