NoD, apparently there was 4t on the loadsheet when in fact there was 7t.
I normally do not like "speculating", but only did it in reposne to what looked like a preliminary report (now appears to be the ASR - I'd be v p*ssed off if people posted my ASRs here!)
Earlier the 3T discepency referred to the Bulk Hold (at the back). Surely if there was 3T
extra at the back, then there would not be a rotation problem? Seems to me that to prevent rotation, we need too little weight at the back, and too much at the front?
Is there any way that a calc error on the part of the airport staff can be traced after the fact?
Yes - I am sure the crew activated this "process", which involves weighing all bags and cargo. But has has been suggested, it is more likely to be more fundamental - whole pallet(s) / bin(s) on Loadsheet and not aircraft (or v-v), or at the wrong end of the aircraft... I am sure EK and JNB know exactly by now - in fact, did some hours after it occurred.
