    You don't have to live with 2' off the arc, simply remove it.

    I like to keep a couple of minutes error on the arc at all times.  If one
    tries to adjust the error out completely, with changes in ambient
    temperature, etc, the instrument could easily end up with an error off the
    arc.  I find that the step of having to read the drum and subtract from 80'
    to find the error is one extra place to mess up.  Since I don't need any
    more of those, I like to stick with the positive error, which is simple
    enough to subtract from the sextant height.
