Are you using a case spreader?
Try moving the carrier .003 closer to the pinion.
Where its at right now ain`t that bad. 
A perfect pattern is`nt easy to get 
The previous setup attempt was with the carrier shimmed .006 closer to the pinion, which gave me .004 backlash and about the same pattern. I'm going to pull some pinion shim and try gain... I kept moving the pinion deeper when I was getting marks on the drive toe and coast heel. My backlash was off too, so I never saw a perfect pattern, but the marks did swap sides to drive - center, coast - toe. I guess I passed it.
I don't have a case spreader, but I have about .010" more shim in there than I can force the carrier in by hand with. I use a rubber mallet to drive it in, and it has some decent drag to it when free-spinning.
