Do you mean the dither alluded to above is cumulative? I was never much good with statistics and remember only that the expectation of the offset after N steps in a random walk is sqrt(N) times the average step size. Not a clue what the distribution might be. Intuitively, I would be aiming for uniform, and randomly adding half a polling interval delay when doubling it seemed to me like it would do that.
