Use of "closest" and "uninvolved" when discussing closest margin. Neither word used when discussing margin distance, etc. when not specific to "closest" concept
Per discussion - "uninvolved" will NOT be included in any of the distance observables. "Closest" will be included for those concepts specific to "closest margins"
