I'm going to assume that you are turning this with the pinion gear because the pattern is not clear with defined edges. I recommend sticking an axle in and use the axle to turn it several times in both directions to get a more clear pattern. Also be sure that the pinion bearing preload is set correctly every time.

The .026 pattern looks pretty good. The .030 pattern looks pretty good on the drive side, but the coast side is a little too much on the root. Go back to the .026 and make some adjustments to the backlash to see if the coast pattern will move toward the heel some. Use the axle to turn it.
