Please pay attention how one determines parameters' signs from either Table. The users of PRW-Tables they pick-up signs directly from the Tables. When using NAO-Tables, it is necessary to study the rules printed on the tables’ margins. This demonstrates how they copied the form of PRW-Tables and trying to disguise it, they succeed only in making complicate rules where rules were not needed, as signs in PRW-Tables are just picked-up together with parameters.
PRW Nautical Tables
The Nautical Tables - NAO and PRW - overlap for the latitude values 18°, 19° and 20°. The number values of parameters P (V), R (p'), (w1,2) for PRW Tables and A/H, B/P, Z1/Z2are the same save for PRW Tables which are more precise as NAO Tables round minutes to integral number.

Incredible
Es ist eine Schande für Herr Majesty's Nautical Almanac Office aus London in eine solche Plagiataffäre verwickelt zu seine !
