Not exactly, this does allow you to "fine tune" a set that already is close
enough, but it doesn't necessarily get you close enough if you weren't
there already. There is a graph in of the hysterisis(sp?) region in the 8/a
book and tuning consists of making sure that the write current and inhibit
current cancel, and that write current from both the x and y drivers will
just flip the bit but not risk flipping other bits.
