    Jared,
    
    My reasoning was as follows.  If you're traveling at 1 knot, that's
    about 1.5 feet per second.  Since that's below the absolute
    resolution of the GPS, it might have trouble establishing an accurate
    course at such a slow speed.  I know that relative resolution is
    actually governing here.  But at some point there's a lower limit,
    where you're going to be going too slow for the thing to figure out
    which direction you're heading.  I thought maybe this would be
    covered in one of the manuals.
    
    I unfortunately used the word current in two senses in a previous
    post, to refer to a flow of water and then to refer to an up-to-date
    speed.
