Naw, Jon was looking for a faux relocation of the cap line. He was 
planning on keeping the keyframe and the hammer strikepoint in the 
same place, hoping that if he moved the stack away from the key 
balance, the new lift point on the rep cushion (3mm distal, as you 
say) and the slightly shortened lever arm of the shank would reduce 
the weight of the hammer as felt at the key. It would, but not nearly 
as quickly as moving the knuckle out or the cap line in (towards the 
key balance).

By the time the initial responses came in, he'd already talked 
himself out if this trick. I admit it is alot easier to move the 
hammer line than the cap line.
