The calculator wants to know how far the ARROW is from center, which needs to include the thickness of the arrow plate too. Typically a -3/16 cut bow has a 1/16 plate which equals -1/8 for the calculator. I can't tell you how often I've seen plate thickness not considered when people complain the calculator does't work for them.
