I've used this identical technique to write hourlong talks -- it works well! The first sentence is the _core_: you write and rewrite this a lot, because the entire talk builds up to it. Next three sentences are the major supporting ideas for your core. They also get rewritten a lot, because again they're really important, they flesh out your core idea. Then you write a lot of detail, one chunk per idea. I'm glad to know the name for this technique, it works really well!
