Formula for a determinate returned parole violator with a consecutive indeterminate new term. To compute the Conditional Release*, use the controlling Maximum Expiration date. The good time is 1/7 of the determinate time owed plus 1/3 of the indeterminate maximum term. *Penal Law 70.40 (1)(b)(ii) prohibits inmates from being eligible for CR before they are eligible for parole, so the CR date is slid back to the PE date and the good time is correspondingly reduced.
