Drive pattern should be a bit more centered (heel-toe) IMO.

No, pinion depth. The shim that goes between the pinion housing and the diff housing, make that thicker by (im guessing) 10-20% and test again.
Backlash is a hair loose too. Range is 0.005"-0.008"

The 14 Bolt Bible By BillaVista I Intend to use this article to gather all the info and pics I can find on the venerable GM "corporate" 14 Bolt (14b) full-floating rear axle, also referred to as the 10.5" (after the size of the ring gear in inches.) There are "other" 14b axles out...

Ok so adding shins will move the pattern closer to the ‘top’, further away from the ‘root’. Is that way you mean by centering? You’re not taking about centering from toe to heel?
I'm talking about toe to heel. Your drive pattern should be centered.
I was thinking that adding more pinion shim would bring the drive closer to the heel, which is what I am suggesting. One section agrees with that, but the "ideal contact" picture says add backlash. You can't do that, because you already have too much backlash.
I'd add some pinion shim, then recheck, if it were my diff. At the end of the day, it's probably good enough, but I think it could be better.

IMHO that's perfect. Nice work man.
My pattern print isn't as clean as yours, and my ratio seems different, but the drive pattern is centered like yours. I've had no issues, and no abnormal wear, after a number of checks, 2.5 years and >20k miles later.
