This is my favorite way too of making half-square triangles. It's going to be great for using my 5" charms. They will come out at about 3" half-squares and 6" pinwheels, so there will be some waste but not terrible and I'm glad to use up some fabric.
Sorry, I don't know the answer to your question. I had a chart for that but the problem is finding it.
