Max wires in 22.5 ci receptical box?

Is this diagram to code in Oregon? One thing I'm not sure on is the number of wires allowed in the top box. If not ok, what would be another way to do it?

In the top box, fill units are: 1 grounds, 2 receptacle, 6 hots+neutrals for a total of 9 fill units. With #12 wire, each fill unit requires 2.25 cu. in., requiring a minimum box size of 20.25 cu. in.
