And that is the problem.
If you want to build a system to catch errors in another system, then you have to assume that everything in the system being checked could possibly be screwed up.
If there is a possiblity that the weight can be input incorrectly into the first system, then you have to allow that the same error can be made if the weight is input into the second check system.
There again, if the weight could be derived automatically from sensors or weighbridge, why would we need the second check system anyway?
