Duplex outlets in series AND parallel after GFCI
Electrical cable/conduit routing must be tree topology
You can also wire things in a &quot;vine&quot; topology, like 12-15-16-17 - after all, a vine is a type of tree.
You can also wire in a star topology (like 12-9-15-14-13). That counts as tree topology also.  (but with many connections, box fill rules must be followed just like anywhere else).
You can freely mix them all.
Here's the acid test: In your graphics editor, take your cabling diagram (remove the non-cablng elements like gray walls).  Now, grab the paint can tool, and pour purple color anywhere on the diagram.  Does it fill the whole diagram?  Then you have tree topology. Yours appears to pass.
