Comparing the NA moon corrections to those in the AA is like comparing the Davies tables to HO 249. The NA tables are only two pages but require multiple entries. The AA tables are single-entry but each half-daily, custom-computed table takes up about 1/14 of a page, so we're talking about 52 pages worth of tables. It just boils down to whether a navigator values time or shelf space more, on a particular vessel, on a particular voyage.
Processor cycles versus data storage.
