There are some specific requirements for early release. The DOC will compute when you are eligible for early release. If you've not served enough time to qualify there, there's not a thing you can do that will get it. Once you are eligible, your parole officer is notified and the make a recommendation back to the parole department. It eventually goes back to the parole board for a decision.
If you think you are coming up on your eligibility date, it wouldn't be a bad idea to discuss the issue with your CPO.
