Generally, the departmental decisions are favourable at about a 60% to 75% rate. If we look at what VRAB does, I would say, and this is off the top of my head, that at the first level of appeal they will probably vary favourably 50% of the decisions and at the second level of appeal they would probably vary 25% of the decisions.
