Greg, I think you misinterpreted the pictures as indicating a ground rod for
each panel. The grounding symbol is used to only illustrate a common
ground. Read the text and you will see that an additional grounding
electrode is not required if a grounding electrode conductor was run with
the service feeder.

The original poster did the job correctly by running four wires and keeping
his grounding conductor separate from his grounded conductor (Neutral).

Since you ran a grounding conductor with the feed to the subpanel, you do
not need to install a ground rod at that location.


Simply not true. Anything beyond a single branch circuit to a remote
building
requires a ground electrode system. The only thing a 3 wire vs 4 wire
feeder
affects is regrounding the neutral at the remote building.
