Assertions:
1) The various 4 star crafting (i60) artisan's pieces compose a set of items
2) The various weaver pieces (i55) compose a set of items
3) Relative stats between corresponding pieces have been constant ( CP 2/3 to CP 2/3, Craft 3 to Craft 3, Control 27/31 to Control 29/33 )
4) The Artisan's Apron qualifies as BIS and has a corresponding difficulty to produce.
5) Meld patterns between corresponding pieces have followed a pattern of requiring the same number of materia but slightly larger materia.

Conclusion: Lacking CP the artisan's apron breaks the patterns between the artisans sets and the crafters AF sets. If it had 2/3 CP for nq and hq it would match them. It appears that rather than being intentional design the lack of CP is accidental.
