And yet Jim I knew that both you and Frank would answer the opposite, without even reading your posts. My point is I have no idea which one of you is right, as I don't study this. But what I know for certain is one of you is wrong, since it can't be mostly raw and mostly graded at the same time.
So what is the point of these surveys? Nobody studies the percentage of graded backs, they just guess at it. Is that serving the OP, and even if he got the correct answer does it make a difference?
