@Charles Kenyon.
Your Quick Style Sampler document still has all 300+ styles in it including List and Table Styles.
There are 23 Styles displayed in the Styles Gallery.
There are 17 Style Set available on the Designer Ribbon.



I believe that it would benefit most users to be familiar with using the Styles Pane to Display ALL Styles ordered by As Recommended with Show Preview Selected. I would change the article to include that recommendation for users to at least look at the entire list. I don't believe most users out there have been exposed clearly to the number and types of Styles that already exist.
