This last part came out muddled.  It's obviously wise to put infrequent
combinations together (like jk), but j and k are both also rare letters
so putting them together represents a wasted opportunity for meeting the
supposed design objective.  Swapping, say, k and r, or splitting jk but
putting e in the middle would surely result in a net gain of "hammer
separation".
