That was actually calculated at BEA report.
Taking into account the 19 "missing" bags (and using 88 kg per male passenger) the CG at taxi with fuel was estimated to be at 54.25, when as per load-sheet that was supposed to be 54.2. Therefore, when the crew fixed the CG before take-off they thought they ended up at 54 when in reality you can estimate that it was about 54.03.
Cannot say if that difference has any effect on aircraft performance, but it DOES sound tiny, especially when taking into account that there has to be some margin to accommodate e.g. the fact that you do not actually weigh every passenger.
