-(The 1/(2(''d''+1)) threshold is meant to allow stacking ''d'' dyads that occur in the chord without having the sum of the dyads have over 50% relative error.)
+(The 1/(2(''d''+1)) threshold is meant to allow stacking ''d+1'' chords, including the original chord, that occur in the chord without having the sum of the dyads have over 50% relative error. That is, you can make a copy of a chord up to distance d away from the original chord without inconsistency.)
 Since a consistent approximation must be unique, it suffices to find the consistent approximation and check the relative error of that one chord to check distance-''d'' consistency.
