In science:

Therefore, the randomness of the pinning term vanishes in the weak coupling limit.
Copolymer at selective interfaces and pinning potentials: weak coupling limits
Once the axis of the pin holder has been made parallel to the beam axis, the lattice plane of each crystal has been determined and either a couple of cylindrical pins or one conical pin is glued to the crystal.

Therefore, if we take the coupling to the disorder potential to be the same, the pinning frequencies of the electron WC at ν and the CFWC at ν ∗ are equal in the classical limit, and likely of the same order in the region where the system is not too far from the classical region.
