Remember that Rebel does not compute the attack tables at all of the leaf nodes
since it does a form of lazy eval.  Leaf nodes form the bulk of nodes and since
Ed reports a x2.6 speed-up when he applies the lazy eval I would estimate that
only ~40% of Rebel's nodes are fully evaluated.  Of course this is only an
estimate and Ed would need to confirm.
