    Looks reasonable, except the point at :
    >>> +15 days ACS ~2 orbits March 3 (=4.063)

    is during the 2nd week of the black out, when only "a few SAA-impacted
    orbits would be accepted". I assume we would not want use that but
    would instead move this point to the first post-blackout date, Mar 8.
