So the ARGN1 value shows correctly the amount you are going to gather from one try. The problem occurs in moment, when there is only like 5 resource left in the worldgembit, then it shows you are going to gather like for example 10 resources, but it will only gather 5 that are left.
I think the problem is that ARGN1 might not be actually real value that you gathered, but only the calculation based on skill, reap, and resource definition.
