Pairs which had good IR for pairs (duality, semiduality, activation) but then have broken.
For cases of people having public data, which is supposed as enough to understand their types.

By the theory IR effects manifest higher when people have intensive, informal and close interactions in cooperations as a friendship. Good IR help to establish good friendship in pairs, when people have high compassion and care about each other to make other one to feel happier, when want to do many things together. Egocentric approach is among what reduces the usefulness of good IR.
Jung types is _one of_ significant traits which influence on how communications of 2 people develop. May exist positive and negative influence from other people traits. Also influence peoples behavior and environmental conditions.
In theory's borders good IR should significantly arise the quantity (%) of emotionally good and stable pairs, but it's not obligate that all people will have this. Especially on long time, as for ~3 years pairs may hold mainly on sexual attraction and linked emotions. It's preferably that a pair existed at least 1 year, so people had the possibility and a time to understand each other and to establish emotionally good relations.

If you think additional kinds of IR as very good for pairs, then may post your cases too.
Mistakes in types and changes in opinions about types (and hence IR) also may happen.
