I was not satisfied with the precision of annual corrections to the Polaris SHA and declination mean value as shown on page 256 of out of date Nautical Almanacs so I constructed a more precise custom Polaris SHA/dec table to be kept with out of date NAs. To use look up year and month for Polaris SHA/dec and interpolate for the day of the month if necessary. See attached custom Polaris table.
