I do a slow wink with the jack tender feeling how the jack gets  back under 
the knuckle I want to feel the jack brush the knuckle but  not too much.  I 
also give the hammer shank  a slight nudge downward to 
see how that makes a difference.
 
Jack too high ? it wont get back under the knuckle.  Too low ?  and your 
hammer line will drift.
