Time to learn model clause

I received the latest paper printed Oracle magazine today. Reading what the soon to be OUG Harmony 2012  keynote speaker has to say in the magazine askTom column. Dealing with the problem of Grouping Ranges.
So many ways writing code. The article introduces PL/SQL, recursive common table and model clause approaches. I just added a SQL and analytic function approach solution to the problem discussion at http://asktom.oracle.com. Not so pretty, but possible. Maybe the model clause version is still the most efficient one for this problem. Should also I start rehearsing model clause to my coding tool set...
