As the others have said ... same beast, just different names!
Keep in mind that the proportions can change, as you wish.
Most commonly it is based on a 9P of equal size sections.
However, you can change that up as much as you want, with a large centre (great for a focus fabric) and can make the strips around skinny-minnies or whatever you like!
Here's a flimsy where I went for the larger centre, but still kept the side strips a substantial size. I have seen some where they are quite skimpy.
