Probably not because you need to get a lot of resistance in the gears to get a clean pattern. I like to use an axle shaft to spin everything as there is a torque reduction and it takes a lot of force, easier than trying to turn the pinion and loading up the ring gear with your forearm or a board.
Also the pattern looks good, I'd run it. Could be a tad deep but it's hard to say when your not setting up he gears and see the progression.

Sorry, could have been more clear, I was talking about resistance on the ring gear and pinion, not pinion preload. I can pull a few thousandths but won't the pattern move toward the heel once under normal driving loads, being much more than I'm putting on it to take the pattern?
