Domingo presents several algorithms based on the 
rational mean.  His Rational Process ARP-2b, for
example, _does_ pick up the fraction you mention
i.e. 635/504 for cbrt(2) or 131/504 for cbrt(2)-1.

There's more source code in another branch of this 
thread over at comp.lang.python, for those of you 
interested in computerizing continued fractions etc.
