To calculate what belongs on Fee Check Summary, we take the standard deviation of all length + girth and weights fields for all items. These calculations are displayed on the far right of FeePreview. Any items that have greater than 3 times (3z) the standard deviation of both of these goes into the Fee Check Summary.
These items should be physically measured and weighed to check the accuracy of what Amazon has listed. Take a picture or two to prove to Amazon seller support if, in fact, your measurements or weight are different.
