GO, I see what you're talking about and it is suggestive. But I don't think this photo is good enough to really say one way or the other. It's just too easy to see things in a lousy photo, especially if you're already thinking it's supposed to be there.

Let's take another tack. If you're interpretation is correct the force on each anchor should be the same ideally. The angle between the left and right anchors looks like about 85 degrees or so. For the 595 lb load that would give a value of 240 lbs on each anchor.

If instead four strands go to the center, the ideal would be 171 lbs for the side anchors and 342 lbs for the center one.

The actual mean values they measured were: 195 lbs (left) 365 lbs (center) 189 lbs (right).

Now any monkey would quickly discover that this anchor binds like crazy. But is this the reason the results do not come close to matching the ideal case? Or is it rigged so that it wouldn't?

I don't know.
