No, 8:0 means to use 8% more weight to the order ...
By coincidence your 8:0 may be appearing to give the amount of extra weight that you are looking for ...
Try a 1lb order ...
Try a 10lb order ...
Try a 100lb order ...
And you will see that between the calculation of the number of boxes and the Tare how the extra weight is added ...
NOTE: boxes round up ...
