9" R&P contact pattern

I'm setting up my 9" with new 3.50 Motive Gears. Backlash is .007 (spec is .007-.009).
Here is the Drive side.

Here is the Coast side

Is there anything I can do to improve this pattern?

I've read through that. It's tough matching my images up against computer generated images. Mainly looking for some veteran advice who's done a lot of them. Thanks though, I appreciate the input.

I sent these pictures to Motive for critique, the tech suggested to add .002 pinion shim. This is what it ended up looking like on the Drive side

Here is the Coast side.

He said that was it, button it up.
