If anyone is interested 5000cc is roughly equivalent to a 32MM.
6000cc is between a 32N and 32NN.
But a jump of 1000ccs doesn’t equal a bump up in one or two cup sizes.
At those sizes they do. Increasing the volume by 20% doesn’t increase circumference, ie. cup size, by 20%. Its diminishing returns:
250cc ~32A (1)
1000cc ~32G (+8)
2000cc ~32J (+4)
3000cc ~32KK (+3)
4000cc ~32LL (+2)
5000cc ~32MM (+2)
6000cc ~32N/NN (+1.5)
7000cc ~32P (+1.5)
8000cc ~32PP (+1)
9000cc ~32Q (+1)
10000cc ~32QQ (+1)
I like where you took this, however, it seems most big implant girls of the past that had 3000cc implants, listed the bra size as J (US size no doubt) after which UK sizes start using double letters. I have made a point before that bra cup size uses the law of diminishing returns and tried to equate volumes to bra size, but used the 3000cc figure as a J since so many are listed as such. It helps when trying to estimate what volume size natural breasts would be, using their bra as a measuring cup.
I think 100cc is more appropriate for a A cup from information I gleaned from plastic surgeon sites, with 500cc being a full D. When we approach the larger sizes, it is very apparent that the law of diminishing returns plays a part; German girl, BustyyJenny at one point held up a R (European no doubt) cup bra which was an ill fit for her (band far too large), but she also holds a sign saying her breasts are 22kg and 21kg, which puts her in the 20k range; from the videos, you would suspect such given her incredibly full, essentially round tubular breasts. I also did estimates on a KK girl at just over 5000cc, given her approximate breast weight, which fits more in line to what I am suggesting; J being 3000cc, an increase of 2000cc equals 2 cups sizes at that point. Past this point, it seems a slightly increasing amount equates to the next size, approximately (Jenny would have rated larger cups if they made a cup in her appropriate band size).
