When the CER provided data for average household usage on the basis of its most up-to-date figures, it examined all households and total water consumption. It worked out an average figure, which gave a consumption level equivalent to a household of 2.6 or 2.7. I do not understand how it can do the same exercise, with broadly the same data but perhaps with a little change, and all of a sudden have 2.6 or 2.7 become four. Will the Minister explain it to me? Perhaps I just do not understand it, but I am happy to learn.
