I have it from a high-level source at Steinway that the back side of this (closest to the agraffe) needs to be high enough that you cannot get your fingernail between the strings and the cloth. It does seem to me that those pianos that do not meet this criterion tend to have more agraffe noise in an unpleasant way. This may be why they have 3 thicknesses of fiberboard on hand, though that's my speculation.
