We used to have a guy here who used a lot of "block weighted" stuff, but his method was different.
What he called "block weight" was putting the CG 3 3/8 from the grip center on the midline with an X-hole 3 3/8 past that, also on the midline.
That particular drill never worked well for me (my pap is only 4 1/8 over), but had a friend who shot out of his mind with it.
