True enough, I could use Ageton's H.O. 211 from an assumed position, but
Ageton's 1961 book "Manual of Celestial Navigation" includes a second table
(actually the first in the book with H.O. 211 as the second) which is used for
the initial table entry in the sight reduction. It makes the tables twice as
long, but simplifies the arithmetic a little. I have not seen this table
elsewhere.
