There are about 40 votes in total each year to vote upon, which is not very different from the number of departments we have. Each of those vote areas might include three or four output classes within them. In some cases there may be only one output class, depending upon the size of the vote that's being considered.
There is a general tendency, as a treasury policy, to try to cut down the number of output classes and confine the expenditure approval to the overall vote, and going on from that I think is a treasury attempt to try to cut down the number of votes.
