yeah, I figured it might be like that CC. I guess it comes from it being a voluntary thing. If you only have one or two examples to go from, the difference can be large, statistically, the greater the number of examples the better the average. As I pointed out to bushy, the fuel costs are way off. Gave me a point to start from tho, and that's what I'm after. Not going to be my money tho anyhow!
