Hi team - yes, Wayne's detail is a key factor on this question. The plating committees recognized that pad size has an influence on plating deposition many moons ago so the plating specifications always dictate a pad size so that everyone is measuring consistently/repeatably. You should be measuring the pads as specified by the specification. Having the "extra" plating on the other pads may not be an issue at all.
