According to the conventional model, gas sublimation jets are streaming out of the surface for the nucleus. Guess what? That seems to have no correlation with the state/rate of rotation. Hmm.
You get more change if there is more solar energy and less change if it is spinning more rapidly to begin with or if it is a larger comet. Larger, rapidly rotating comets are not going to change their spin status very much.
We expected that the fraction of the surface of the comet that is active would also be a controlling factor, but that proved not to be the case.

Another issue with the conventional model that a comet is a dirty snowball.
According to the conventional model, gas sublimation jets are streaming out of the surface for the nucleus. Guess what? That seems to have no correlation with the state/rate of rotation. Hmm.
I believe this is another win for the electric comet model. We could see an entire re-write of the dirty snowball model by the end of 2014. Sacred cows make the best hamburgers!
