I understand the theory behind the full bust adjustment calculation considering the difference between upper bust and full bust to be all tits, but as a person with a broader ribcage and smaller cup size (bra sizing I'm something like a 40A, which is a difficult size to find in most brands) it's looking a little dicey.
I'll try it as explained first, of course, to see what happens, but the FBA is on thin ice right now.
