Yes.

I've uploaded my old final report to
/~rudenbiz2/physics/pubs/
What we've done so far here is straightening out the most basic
analysis. Once you get the error in G down to the percent level,
you'll want to perform a more accurate analysis. For example, in your
calculation of the torsion constant, you have negected that fact that
both damping and the gravitational field *gradient* perturb the
oscillation period. Also, you neglect the gravitational attraction of
the more distance stationary ball on each pendulum ball. I don't know
what Cavendish himself considered, but these three effects are
considered in my final report. It turns out that the field gradient
effect actually cancels out if you take the equilibrium theta
difference between M and M' tests as we have - but you need to prove
this for a valid analysis.
