Good question. If they'd at least made them 100 BCD, they could have interchanged with the Campy NR triple inner. Kind of like Zeus chose 120 mm, just 2 mm less than old Stronglight. I don't think I've ever actually seen an Avocet crank with the 102 inner ring mounted. Probably because, once these were out of production, the 102 rings were hard to find, while 74 was much easier.

Large outer ring is 144 BCD Middle ring is 102 BCD Small ring is 74 BCD

I need a couple of middle 102 bcd rings. Is there a source for these oddball size rings? Why in the world would they even make these arms with a 102 bcd?
