The opening of a pad is determined by the thickness of the pad, how deeply the pad is glued into the pad cup, the thickness of a felt or cork (that silences the opening at its limit), AND the geometry of the key, which can easily be modified, by slightly bending the metal, either on purpose or by accident.
The register key needs to open only as far as it needs to, to reduce the 'fuzziness' of the Bb to a minimum.
Other factors also contribute to the fuzziness of this Bb, e.g. shape and material of the pad, the design & location of the vent itself, and any blockage in the vent.
