The problem is that having a 3:1 contrast between body and link text is all fine and good, but does not take into account the actual background color. You can't distinguish black and grey if there's lots of another color (white, in Eric's case) between them. So you have 3 colors in play here, and that increases the problem of being able to distinguish between the first two.
