Thumbs up Gear pattern feedback

Hey guys just curious what you thought of my current gear pattern with motive 4.10's. I started with a .26 pinion shim as my starting point. It was too shallow as I expected it was riding out the face. Jumped to .30 it was getting closer but still too shallow, so jumped to the next shim .36 and it looked pretty close, I tried my luck and tried .38 and I think this is acceptable, I've kept backlash around .007 to .009 which are motives specs.
Here are some pics at .38 pinion with .008 backlash

Here is a link to the library same pinion depth just different amount of marking compound to oil dilution.

Thanks in advance for the input.

Quick bump, this is the same specs as above I just took a vid from both drive and coast so that you can get a better perspective, I think this is deep enough, I applied as much drag as possible to the pinion with a rag and turned the ring gear with a wrench, to make it spit a readable patter.

I thought about dropping .002 but I think I will just run this as it seems to get the best depth even though it might be a smidge deep.
