FWIW, the choice of specific rings and crank also will vary the distance between rings. Basic Sugino rings for example, do not have the wonderful clearance of their OEM rings that come on their complete cranks . They are set and formed completely differently. So every setup is going to be unique .
Also, there isn't just one chainline that works either. Spec's are given not as absolute rules, but as the measured spec of the component with other like or branded components . For a middle ring you have room to "play" so to speak and the chain will be fine .
