    I don't buy it! First, if you sink a ship, you lose a customer. That's big incentive not to dirty your tables. Second, these tables --whichever ones they might have been-- would have been published in last decades of a century-old method.

    Slocum probably was using tables keyed to that era's Bowditch. The prefered method then was Chauvenet's which was relatively new at that time. Slocum probably learned a different method when he was a commercial ship captain. The end of the century method may have puzzled him, and I would bet that details of Chauvenet's method would surprise a lot of the mathematically-inclined lunarians who follow this list.
