Implant Size and Bra Size:
Generally, each 150-200cc increase in implant volume can translate to about one cup size increase in bra size. 

This is somewhat incorrect, especially once the sizes get big enough. Cup size goes up by a percentage of volume instead of a set volume. Typically that increase is around 12% - 12,5% but different measuring systems work differently. EU sizing has the smallest jump that I'm aware of, anything using inches has the largest and for example Ewa Michlak is in between as they use 2,5cm increments for cup volume. So this is somewhat accurate, until the sizes get big enough.

Its around 200ccs near the average, then around the bigger end of normal size its around 360ccs and so on. When I'm upsizing my current bra, that difference is approximately 960ccs.

Almost no one understands the sizing systems. They're weird and illogical, I think the best would be to have the cupsizes categorized by breast volume, but that would give manufacturers a bit of a headache as they couldn't just add increments of 2cm, 2,5cm or 2,54cm/1".
