Strong
A high score means the question of whether to stay is closed: you treat this bond as settled rather than under review, in a bad stretch you assume you will get through it rather than weigh it up, and an easier option elsewhere gets no serious consideration. This is the component that holds a relationship together when the other two dip, which is precisely why it is measured separately. Its blind spot: a decision outlives the reasons it was made for. The same score comes out of a bond chosen afresh every day and one nobody asks about any more.
Moderate
A middle score describes a bond you are in without having settled. Usually that means the effort is real — you give it time rather than goodwill alone — while the long horizon is honestly open: you do not picture the next few years without them, and you do not picture them with them either. This is the accurate reading for anything early, anything at a distance, and any stretch where the answer is under review. Unlike passion, this component rarely drifts on its own: it moves when something is decided, so a middle score usually means a decision is pending.
Faint
A low score says this bond is not currently held up by a decision to keep it. That is the accurate reading for a new connection, for a relationship that ended and still occupies you, and for a stretch where the answer is being reconsidered — and it sits perfectly well alongside strong feeling: the most intense bonds people report often score lowest here. The scale rules out exactly one thing: the assumption that the relationship will hold on its own, with nobody deciding. Whatever is holding it right now shows up on the other two components, not on this one.
