    I think you are doing quite well with the pacing.  On fairly
    even ground, you should be able to get consistency within
    ten percent; and you are doing better than that; around 2.5
    to 6 percent including the error in sighting.
    Just a thought, but do the pacing and mil reading before you
    use the laser; and then choose a new target.  That way you
    might be able to eliminate unconscious bias in pacing and
    measuring.  Also, as an active marine, you probably did too
    much range estimation in the 200 to 800 yard bracket; so try
    something further away and more unknown in size ... such as
    a large rock out in the middle of nowhere.  :-)

    The Canadian army still has the "Pace Stick", looks like a
    longer swagger stick of varnished wood with brass fittings
    ... or at least they did at the last Armistice (Veteran's?)
    day ceremony on November 11.  The stick opens out and locks
    at a couple of different  settings as desired, and the spots
    for posting can be measured as with a pair of dividers on a
    piece of paper.
    Or, I have been told it can be used during a march to
    regulate the pace length.  That doesn't seem feasible, but
    just because I haven't seen it, doesn't mean it can't be
    done.  I would be interested to know if it is used in the
    Australian military.
