Will to Power, Order of Rank, Comprehensiveness

One characteristic evaluated by the Order of Rank that expresses the Will to Power is obviously Strength.  Another is suggested by Nietzsche's reference to "more comprehensive states", in his discussion of Order of Rank in #257 of Beyond Good in Evil, at the beginning of the chapter in which he explains 'What is Noble'.  Now, 'comprehensiveness', can be defined as a relation between a Multiplicity and a Unity, so that 'X is more comprehensive than Y' = 'X unifies a greater multiplicity than does Y'.  Thus, that a more comprehensive theory is often characterized as a more 'powerful' one suggests that Comprehensiveness and Strength are both not merely appropriate in an Order of Rank that expresses the Will to Power, but are equivalent, if not identical.
