If you agree that suffering is (at least) unpleasantness + desire, and both components can vary separately in intensity, then there isn’t really “one intensity” for an experience of suffering, but two, one for each component. Suffering would vary in intensity along the two dimensions of unpleasantness intensity and desire intensity.
You could have some function that takes both component intensities and spits out a “suffering intensity” or “suffering badness”, though.
