Awesome tutorial on cte, concise and crystal clear. It was a bit frustrating for me working in sql and not being able to chain the results or save the objects to be reused. From now on, after your cte tutorial, it will be more funny and pleasant working with sql as never before.
For greater readibility, I would like to suggest you to consider some formatting or beautifying your code, specially your inner inner query/the derived table from the first join
Keep it up Sir, you are a legend!
