I've been having this issue for about a month now and didn't exactly want to pester the guys at Polycount of this because I felt that it might just be going over my head,but I've no clue of what's happening.

As seen in the above,there are visible square patterns(which I presume is the wire of my low poly) on both images.It doesn't matter in which software I retopo in.It also doesn't seem to care for either baking method...I thought that it might just be that the UV's were flipped,so I checked to no avail.I also thought that it could possible that rays were being fired through the openings on the torso it self(Where the arms and legs would be)but that wasn't the case either I'd guess.Finally,I just did an entirely different Torso bust with no opening and baked in XNormal...Didn't work.I'm pretty confused here and would REALLY like a bit of help.

So at the vertices, the difference us very small (hence the dark grey) and towards the centre of your low poly mesh the distance increases (planar polys in the low, casting against a curved surface on the high) so it gets lighter between the vertices.
Here's a 3D view
