How to correctly input cumulative, split sieve data in Lab Testing Module?

Our company is just starting to use the Lab Testing Module and the Lab Testing User Guide isn't very user friendly for a novice gINT Administrator. The lab's procedure is to run sieve analysis with a cumulative weight of coarse and a cumulative weight of fines (splitting the sieve between 4.75mm and 2mm). The lab also zeroes out the scale after putting the pan on so there are no tare weights in the "Wt Sieving Tare Coarse" and "Wt Sieving Tare Fines" columns.

No matter how I go about inputting the data it 1) does not split the sample; 2) does not calculate the fines content of each individual sieve correctly; and 3) over calculates the weight of fines tested.
