For [N-Q] 'outward' would be ambiguous, as it would require some advanced geometry, which most people would not master, to decide whether the adjacent diagonal or the orthogonal continuation had the smallest angle with the N leap.

Another possibility is that [N-fQ] could be interpreted as a combination of [N-fR] and [N-fB]. I think of 'outward' in continuations as excluding any crossing of a queen's path from the starting square.
