Wait… Ain’t that backwards? I’d expect how much X is attracted to Y today to be a better predictor of how much X is attracted to Y if the two of them have known each other for ten years than if they have for ten minutes. (OTOH, people talking to one another decreases how much different Xes vary in how much they’re attracted to a given Y, but probably that’s a smaller effect.)

The point is you have fewer potential mates, so it makes sense to devote more effort to changing preferences.
