There is no bill in the works that will drop an 85% felony to 65%. If anyone writes and say there is s/he's lying and you should go on to the next e-mail.
There is a puzzling piece of information in your question though: normally if you get first camp you get 3 days credit for every one day served. An 85% inmate would not be allowed to work in a fire camp. You need to speak to a prison lawyer to see what is going on.
Now, if the inmate makes a deal for workcamp that is predicated on credits, he could still make a collateral estoppel argument against not getting the credits, right, guys? I know that its a long-shot, but I have read about it in the past.
