I agree, I would have thought that in the mild climate of Launa Beach CA, you would have had more fusing.
But none the less this is interesting. I've never seen another coiled tree, as far as I know, you are "da first". Boldly going where no man has gone before. LOL
I like it as an experiment. Keep it going. I bet by 10 years, it will have more fully fused and begun really smoothing out.
