    The times given have a constant difference,
    except the last one, 13:07:57 10-MAR-08
    which shows a 4s increase in period.
    However, elsets from the last 6 h or so
    still show MM=16.039, not consistent with the plan given.
    Changing MM to 15.93573800 matches the 90:17 nodal period,
    but even if this MM decrease was achieved on time, it would not 
    retrieve the 7 min early transits that are already present.
    This MM diff, if it has happened, amounts to 9m/day, so unless
    you get newer elsets from SpaceTrack, you may want to
    experiment with that MM in their recent 08070.11692042 elset.
