OK, the guy predicting the "wobble" (nutation) is predicting something on the order of 1 part in 30,000,000,000. So it'a not as absurd to make the claim as it seems, although measuring the affect (and not measuring something else instead) seems tough.

We'll see if anyone is brave enough to submit a paper for peer review.
