Where a sentencing judge orders a sentence to be served cumulatively upon 'the sentence presently being served', the ordinary meaning of that order is that the sentence is cumulative upon the existing total period of imprisonment faced by the prisoner at the time of sentence. Incorrect information about a prisoner's full-time release date that affects the application of the totality principle enlivens the appellate court's discretion to intervene, and the appropriate remedy may be to specify the particular sentence upon which the new sentence is cumulative rather than using the general formula.
