Close, but no seegar- - - - -the pattern needs to move a little toward the outer diameter of the ring gear. Are you putting the brakes on the pinion flange in any way? I usually have someone wrap a couple of turns of rag around the pinion flange and hold it tight while I turn the ring gear back and forth with a box end wrench on one of the ring gear attaching bolts. It makes for a more distinct wipe on the teeth that way.
