    The calibration of January failed when I used the recommended 5 hours. Last night it failed again when I used 7 hours.

    So now my question is, how long should I keep the MBP sleeping then?

    How do you mean by "failed"?
    There is no notification as to whether calibration has been successful, as long as you follow the guidelines you should be fine.
