In a case similar to that one, they had negative results. The results are quite mixed, and I think they were also potentially influenced by other sorts of factors. As I said, it's too bad the experiment didn't run longer, because we would have had more evidence to try to make a determination on this. Unfortunately, in the case of Peterborough, we don't really have that.
