Personally, I think I would have graded the card good to very good, but I agree that Dave's super-sized image shows the defects well. That is why I personally think the C scale is pretty worthless for bidders, because most cards get graded at the top end, which is good for sellers, but not for buyers.
But Dave is light years ahead of many of his competitors, many of whom have fuzzy photos and trouble finding obvious defects.
