There is also in the Treasury Board statistics an analysis of that. They do have the average cost per request. During the period of 1983 to 1992, the average cost was $1,000; from 1993 to 2002, around $980; and from 2002 to 2012, $1,300. That came down last year. It's a little bit less, it seems. Those are the average costs per request.
