To be honest i'm somewhat cautious there as there are possible problems and caveats, we had recently a tailstrike because a crew used the wrong weight for take off performance calculation and thrust and speeds therefore didn't fit.
Anyway, we do prefill the FMC with the ZFW from our OFP and crosscheck any deviation from that weight with the final loadsheet (only FMC figure that will be entered apart from MACTOW). Anything more than a couple hundred Kg (lets say more than 200kg) will be crosschecked against differences in passenger load, freight, baggage weight or comail. Those figures will be crosschecked with the ramp agent who has the latest weights himself and the paxload from the boarding gate. If there is any confusion especially in passenger numbers we will do a headcount (usually at least two FAs counting, better three). Baggage and freight is usually weighed before loading, we only have to crosscheck that if some of the freight didn't fit.
If there is any doubt that transmission of the figures was faulty without ruining the whole loadsheet layout (very far fetched) we just use the aircraft mobile phone to call the CLC and talk to the guys who did the loadsheet.
So far we never had a transmission problem with partially or wrong infos on the loadsheet, it either arrived or didn't, in which case we get one via a SITA terminal.
