What Is The Differences Between Size to Size in Cc's?

Hello I put 485cc extra high silicone implants, in front of the muscle! At the time I was undecided between 450cc and 500cc and the doctor put 485cc _ , and I think I should have put 500cc, 15cc but I also think that it makes no difference right? Given, speaking on extra high profiles, from how many cc that makes the difference between one size and another? 50cc? 100cc difference? Regards
