My last fill

Hi everyone one, well I have a bit of a question for someone to answer for me. I ahd to locate a new fill Dr. he is a regular surgeon that practices in Bariatrics, he is very good. I had my first fill with him and he had all of my paperwork from my past Dr. and he even showed it to me and went over it with me. He proceeded to give me the fill and when he inserted the syringe he was able to check the fill and match it to the last time I was filled by the olf Dr. I had 5 cc in my 10 cc band according to the old Dr. well I actually had 7 ccs and not the 5 ccs, he said he did not want me to gt over filled and there is a difference from over filled and tightness as he put it, well he gave me 0.25 cc and I feel fine. Now in the past my old Dr. would fill me at 0.25 ccs and I would get way too tight and he would take it out and then put it back, seems like he or someone fudged on my records. has anyone had this problem before? please let me know
