Still I don't see any sense. The data entered into each FMGEC is identical. Why should it in turn supply FCMC with different data and not once in a while but quite often? What kind of processing is going on with a simple entry of CG and ZWF? It's just what it is and doesn't require any processing. As long as aircraft by itself is not capable of calculating the actual CG and weight, all calculations around the initial pilot data entry are useless.
