The jack has to be out of the way of the knuckle/roller when the hammer rebounds from the string. (one of the benefits of aftertouch ;-) Too much aftertouch and you compress that stop felt. Too little or none, you get bobbling or blocking or at least a strange feeling as the knuckle pushes the jack out of it's way. Conrad Hoffsommer, RPT, MPT, CCT, PFP, ACS, CRS.
