I believe FSA's 30T inner rings are relying on a 90mm BCD as used on this crankset:
FSA SL-k light Adventure Modular BB386EVO - FULL SPEED AHEAD
Pulling the teeth closer to 4 bolts by relying on a tooth count being a multiple of 4 doesn't work for 30T.
Gotta love the 'simplicity' of double cranks and now the proliferation of new BCDs and crank styles to overcome the inherent limitations of only having two chainrings, while still not addressing the lack of range. Triples FTW, as always
